Man, you can shoot anywhere. I have shot:
1) in my trailer home in a park in Kansas,
2) beside my trailer,
3) in a civilian hotel room,
4) in an army hotel room for 4 months at Ft. Sill, OK,
5) in the workshop at home,
6) in an appartment in Minneapolis, KS while student teaching for 5 months,
7) assorted roadside parks, rest areas, and break stations,
lots of national, state, and local wildlife management areas (roaving. Carry ONLY blunt/judo tips and you'll likely be okay if you have to explain yourself).
Your opportunity to shoot is limited only by your imagination, and perhaps your ablity to sneak in the stuff you need.
