Gillett-Campbell [KGCC] to Rapid City [KRAP] IFR with Beyond ATC

A 1 hour 11 minute uneventful USA flight from Northeast Wyoming to South Dakota in the Black Square A36 Bonanza at 9,000 feet. The terrain is primarily rolling hills and plains. I used "Beyond ATC" for ATC control and it was perfect - from departure to destination including vectors.
