I don't want to be the party crasher but:
...we have all played Airsoft with teams of five out in some woods...
Am I the only one who caught this?
Brendan, just so you understand (and in no way I want to sound mean or anything), the fact that airsoft guns looks 100% like real guns to the mundanes, it's generally a very bad idea to exhibit said devices in "some woods".
Then again I don't know what "some woods" means to you so maybe there's nothing to it but better be safe than sorry... When you play, make sure to do so with good safety measures (make sure to have AT LEAST good goggles, rated for high-speed impact or of ballistic grade; want to be sure? use full on paintball mask if in doubt)
But more importantly, make sure to do so on a field you have permission to be (nothing owned by some guy, or the city, or the gouvernement, unless you have written permission to do *airsoft* activity there). But also one that you are 1000% sure that no other people unaware of your activities could wander and have some panic attack, call the cops and that one of you guys get shot at... by a .40 or 9mm glock handled by an emergency task force officer.
I'm sure you understand how this could ruin your game... And if you are wondering why a lot of people here jump the gun (no pun intended) and sounds often aggressive or harsh toward underage wanting to or playing airsoft, it's because of those kind a "mistakes"; Accidents happened in the past, will still happens, but the idea is to try and lessen the odds.
