Fair enough. Was just going to say that if you enjoyed paintballing you'd love airsoft, if that were the case.
See if you can't find a game to go out to. You may not be able to play, but if you show up, and act maturely, and are a generally good guy, people will likely not have a problem letting you check out their kit, and if you play your cards right, you can probably get a bit of shooting in. Some (and I have to stress some) fields/groups will make exceptions to the 18+ to play rule... but you must prove yourself to them.
