I've done lots of off airport flying in Ireland. Gone from it a few years now while other notions were explored like twins, aeros, amphibs, tourers, rotax etc but will def go back to it in 2018.
High wing, manual flaps and 8.50x6 tires will carry you a long way. If you read CC Pocock on Bush Flying he can do alot with a humble 145hp 172C.
