Bobbie was born in Potter County, SD, and lived all his life in SD. His first interest in flying was a big tree behind his folks house.

He learned to fly in a Super Cub. He took his instrument time in a 150 Cessna. He's also flown a 172 Cessna, a 182 Cessna, an Aeronca, a Piper Pawnee, and a 250 Piper Comanche.

Dale grew up in the Sandhills of Nebraska and graduated from Valentine Rural High School, Valentine, NE.

Dale's grandfather, uncle, and cousin also were pilots. Dale earned his private pilot certificate in June, 1993. Family life took priority for a few years so not a lot of flying was done until 2015 when he purchased a 1952 Cessna 170B. He continues to fly as much as possible and has over 500 hours in it since the purchase. Dale has also owned a Rans S6-S, which was purchased for the purpose of getting more hours for his son, Dean, who is the 4th generation pilot of the Knuth family. Dean is pursuing a professional career as a pilot. Dale and his wife, Glenda, have three children and one grandchild. Dale is a member of EAA Young Eagles Program and has given over 100 kids a ride in his Cessna. He also is a member of AOPA.

Bob has lived in Pierre the majority of his life. While growing up he recalls catching the flight bug around the age of 6 on a flight in the co-pilot seat of a Piper Navajo piloted by Bernie Christensen, who was a friend of his grandfather and father. Bob’s father was in the USAF, grandfather a Navigator in the Air Corps of WWII, and great-grandfather a GA pilot. Bob took an introductory flight in a Cesena 150 in 2010. He resumed training in 2015 from Wright Brothers in Mitchell while he was overseeing Fischer Rounds Real Estate in both Mitchell and Pierre. Bob passed his checkride in 2016 with DPE John Barney. With new certificate in hand, Bob and a local instructor flew to Tennessee to pick up a 1967 Cherokee 235 that was once owned by Hugh Downs. The 235 provided many hours of commutes and adventures for Bob and his wife to towns in SD, Colorado, Kentucky, and Arizona to see family and friends. Bob sold his Cherokee in 2018. He went to Riggin Flight School in Madison and earned his multi-engine rating. In 2019, Bob bought his current plane, a 1964 Twin Comanche with Robertson STOL kit. He earned his IFR rating in the Twin with the help of Morris Riggin and Heidi Stoeppler in 2020.

Clark Family Dental Center was opened in 1976 in Clark, SD, and still practices dentistry four days a week. It was an introductory airplane ride certificate that his staff gave him that got him started flying in 2004 at age 55. Harvey travelled to Watertown for flight training in a Cessna 172, and later trained at Clark when the CFI flew the plane during the fall & winter. Harvey finished his training at Marshall, MN, and did his check ride there. In 2009 Harvey completed a mountain flying course in his Cessna 172 (180HP) put on in Denver by the Colorado Pilots Association. Each of the 15 students had an instructor, and flights were made to five high altitude airports in Colorado. Harvey used that experience to fly via Bozeman, MT, to visit his sister in Coeur d'Alene, ID.

In his early teens, Dwayne worked as a flagger for aerial applicator George Grubbs at Rosebud Aviation in Gregory, SD.

LaFave was the first South Dakota aviator to visit all the SD airports with his “FLY South Dakota Airports!” Passport book in hand. LaFave's interest in aviation has roots prior to his birth, when his father Sam was with the Army Air Corps in WWII. Following WWII, Sam purchased a 1946 Taylorcraft and used his GI bill to join the fast-growing ranks of GA pilots. Dwayne's son Jeff began his flying as a De Smet High School student, by traveling to Brookings for instruction, earning his private license and instrument rating through the South Dakota State University aviation program. Retiring in 2016 after 45 years as a public school educator, LaFave will be spending more time pursuing his interests in aviation and music basing out of De Smet and the Black Hills.

After retiring from teaching after 37 years, I am still subbing -- so I passed the 45 year mark in education – and I'm still getting educated! Teaching has really changed since 1972…all a person needs is thumbs! Haven't gotten back to flying, but continue to ‘barnstorm' on a daily basis, pulling hay out of the barn to feed my three horses, sometimes in a storm! Enjoy getting together with the other SDPA members, however, and wish I could contribute more to the association via flying experience. But I hope to explore more remote and unusual airports however I get there so I can share some fun experiences in the newsletters in addition to news from my region. Sometimes getting there is the easy part, being there is a hoot. Sunny has been a SDPA member since September 2012.
