Fearless Tower
Touchdown! Greaser!
Alot of small airports, especially grass strips don't have parallel taxiways. You just self announce your tail # and say "is backtaxiing on 17" and announce again when you're clear of the runway.
Sometimes even at a towered field with parallel taxiways, they will let you backtaxi - When I was doing my night landings in the Duchess for my commercial, MYF tower let me taxi back on the active each time (club policy prohibits touch and goes at MYF in twins so each landing was a full stop.)
