The first iteration of a WooCamp invite, in 2010 I created it in the fashion of a complete National Parks Themed guidebook. Items in the invite include permit style rsvp (with carbon copy) and pre-stamped return envelope, guidebook highlighting features of the campsite and things to be careful of, a large fold-out topo map with detailed direction instructions on front and back, All encased in a hand made envelope with twine clasp.
