There is a golf dome in the city near here, and a club used to fly in it. However, they apparently charged a quite high fixed hourly rate, so when not enough guys showed up to fly on a night, it was too expensive.
It worked out just as well though as the airport lets them fly in one of the huge hangars now for free. It's not heated, but there's no wind at least, and it's cool that they can fly in an aviation setting with the big jets sitting parked. It's funny how nobody is worried about foam planes hitting the jets in the hangar, but outside they are a deadly weapon!
