After sitting in Thin Air puzzle cache for one year, the sleeve was mildewed and the laminate had separated from the coin photocopy. The ink has bled a bit so tracking number is difficult to read. I have washed sleeve in vinegar to kill spores, dried it out, wrapped trackable in heavy clear shipping tape, and added a taped card stock tag with tracking number and goal:travel. Traveling to Michigan next weekend to finish our Jasmer challenge so I'll drop in another state. Hope this moves a bit faster now!
