Come of down to Trek. Death is right JOC (at his link) and CAC (our link
http://airsoftcalgary.ca/forums/index.php) are the two main communities for Calgary.
We (CAC) currently host the Wednesdays there though we are open to every one for every community
. Cjay I believe has moved his Mondays to Tuesday and Im pretty sure ISSA still hosts Sundays like Death mentioned. So as you can see we have enough to suit most needs of nights.
Come on out for a Wednesday and we can get you AV'd as well. Open up the rest of the site to you. Add a bit more reading for ya.
Either way hope you make it out to one of those nights. Im sure you'll have a blast.
