I have not done a vanity plate. But there are gun stickers on my vehicles. The forum sticker on the back glass, a Got Sig on the bumper, NRA sticker dead center of the bumper. I understand the I don't want to advertise mentality but I honestly don't give a crap and I like the stickers. In my small town a lot of people know me anyway so it's no secret my interests.
I keep wanting to see someone join the forum that has seen my FTF sticker. No luck yet though.
