I've started collecting a sticker and/or patch for parks that I've visited, but I'm struggling for a good idea of how to display them. I don't want to stick them all over my car. The idea of framing the patches is okay...I dunno. Has anybody come up with a cool/fun way to show off all the national & state parks you've visited? I thought about buying a map and sticking them on it, but once I start going cross-country that'll be space-prohibitive.
