Folks, looks like this one is a goner... 😟😟😟
Here's what I got:
"I'm afraid I suspect your TB got muggled. [...] I didn't see it next to the cache, but did notice your [laminated] paper description sheet lying wet on the ground about 10 feet away from where the cache is located. Since the cache is located near the rock n roll hall of fame, there is a lot of muggle traffic in this area. I even bet homeless people may have even camped out here near the cache as it appears to be a sheltered place in the bushes within the downtown area."
A WWFM event was held very nearby on 05/10/2008, and no-one recorded it as discovered. Also, a local geocaching forum posting on the event (and the TB / cache) delivered no results... Time to call it quits.
Darn... If only it was placed INSIDE a cache, not OUTSIDE next to a micro. 😡
