My husband and I are fairly new to caching, but we've definitely seen a variety of SWAG, good and bad. We hit an ammo can just last week with a used blistex, a dental floss/toothpick, and a package of fruit snacks that might have been years old. Gross! We cleaned all that out and added some nicer things. I always carry a small shoulder bag with my supplies and a bunch of handmade charms/trinkets and nice party favors from Wal-Mart with me when I'm out caching - it makes me smile to see someone comment in their log about taking something I've left.
