Why would you want a sticker "outing yourself?" Although it seems that many FFDOs have the "Terrorist Hunting Permit" stickers.

My bag is plastered, but there is a good reason for that. The stickers hold the thing together! Along with duct tape on the inside.

My stickers are from places I've been, airports I've been based at, commuted from, airplanes I've flown and a couple from my hobbies. After two furloughs, four airlines and some part 135 flying I have quite a few stickers that reflect my "experiences."
