Welcome Jenword! It's so nice to see you here! And, David's right... it definitely sounds like you're experiencing what we around here sometimes call "Brokie fever"... and it's something we've all experienced at some point or another since discovering this wonderful movie and story. The initial stages of discoveing Brokeback are so exciting and amazing... I remember what you're going through very well.
It sounds like such a great way to start your journey as a Brokie by attending the big L.A. screening! I bet that was so much fun. And, you're right that a lot of BetterMostians and folks from the other Brokie websites were there too. So, you were definitely surrounded by some serious Brokies there. I wish I could have gone, but I'm in Pittsburgh and couldn't make the trip out there.
My name's Amanda and I'm one of the co-mods over in the Social Events forum, where we have lots of threads and subforums about upcoming and past real-life Brokie events. Some of these are major, big-group pilgrimages out to Wyoming or up to Alberta (for example, as Dev mentions) and some threads are about much smaller, more casual events involving only a few folks... and everything in between. And, we also organize online activities like chats. So, please stop by!
