If you want to avoid drama, definitely don't go to TGR. To really avoid drama you have to not go to internet forums at all.
Epic Ski doesn't have much in the way of snowboarding discussion.
I haven't found a better site than this for discussion specific to snowboarding, even though there are only around 25 regular posters from what I can tell.
There have to be more than 25 regulars on here.
..I'm counting myself as a regular...maybe I think too highly of myself.
