Check the threads for outdoor games at the TWAT field or the Alpha Site field (about 45-60 min West and East of Scarboro respectively).
99% of all players I've met are real decent guys/gals with a good attitude. Sometimes at the beginning of a game the noobs have a bit of a hot-shot attitude or a fast mouth, but a few hours of play sorts 'em out.
Talking to a player and getting advice on guns/gear in person is always more helpful and informative when it's in person rather than on an internet forum.
But I will say that somebody in Stouffville or Durham has got to open up a private field- I'm sure there's somebody with a great piece of wooded area in a somewhat remote area that would be suitable for regular games...
Just sucks always having to drive so far for good outdoor games.
