I'll offer that you won't have much free time that is between daylight hours as a young MX officer at Lakenheath. Between prepping for deployments, inspections, the grind of normal ops, and sorting out the craziness your troops were able to get into, Lalenheath seems to suck away all your time. It's a great place...very awesome in its own way. It's just not a great place for a hobby that requires any kind of consistency. Save your COLA and blow it on neat GA adventures when you come back to the States. There's no reason you shouldn't be able to knock out a tailwheel, a seaplane rating, do some acro training, or get a multi when you're home on leave or back in the States TDY.
