I am on xdtalk and longrangehunting.com. Mostly for the articles on long range hunting(nobody there whines about the "ethics" of a long shot). I think i have yet to post on either of the other sites, mainly use them for knowledge base.
The back and forth here is generally more entertaining.
"The spirit of resistance to government is so valuable on certain occasions that I wish it to be always kept alive. It will often be exercised when wrong, but better so than not to be exercised at all." ~Thomas Jefferson
