I don't need to give you the links to all the stories about this and that proposed law that wants to steal our freedom. I expect that anyone who reads this blog has already seen them, and if not, Google is your friend.
But I am going to give you these links:
List of US Senators snail mail and email addresses plus phone numbers
Find your US Congressional Representative
Links to the 50 states' governmental web sites, which ought to get you to those worthies
I trust you'll put this information to good use.
