I still get their mailings because I was a member 20 years ago...I take their free stickers and throw the rest away.....of course I stlll get phone call from the FL State police because about 10 years ago I once made a donation to them - now they call me every year - I keep telling them I'm on Do-No-Call list - but they never listen.
as for gun groups, there are better organizations out there
Gun Owners of America
"The only no-compromise gun lobby in Washingotn" - R. Paul (R. TX)
another really good one
Jews for the Preservation of Firearms Ownership
