Sorry about the bad links. Suddenly, they don't work for me either.
Kulhal: They are very similar, but stamped instead of burned.
mpilchfamily: They do not say trackable at Geocaching.com, but that's the only place I've found that does trackables.
rrgoudie: Didn't see it there, either. Interesting site, though.
keewee: I'm not entirely sure how to do that. I finally uploaded the photos to my log from the cache where they were found, and so I think you can see them by looking at the gallery on my profile.
Thanks for the replies! Very encouraging, as most discussion forums I post to have lots of views and few replies.
