It's a place that's both tame and wild at the same time. Respectful without management interference. Part of it's a rather wide diversity of interests, hobbies and experiences.
I'm a member number of boards but find none better than this.
The High Road is a little on the strict side as far as topics and responses go, where as many of the other general topic boards can get a little nasty. Possible too many Monday Morning Quarterbacks with emperor complexes
All the boards about one make of gun (S&W, Colt, Glock etc) and single interest boards (SASS, Precision Shooting, Accurate Reloading, etc) get boring after a while because they're single topics. Great place to go and look up information or get answers about those items. I have a friend who runs a large S&W Facebook group, but I can only look at so many pictures of S&W Revolvers regardless of how many shares of stock I own.
One very interesting forum, I really like and should spend more time there, is Accurate Reloading.
http://forums.accuratereloading.com/eve It's truly an international board, covering many topics besides reloading. I posted a question about chronographs there once and Ken Ohler was who responded. It's has an amazing and overwhelming reach.
