hoys: Stopped by today, and the cache is missing. Sorry, folks. I don't have a way to replace it, so I'll free up the spot for someone else to enjoy. Hint: Go with my original plan, and attach the cache to the bridge somehow (I had originally attached it with large magnets, but old army surplus speaker magnets are WAAAAAAY too powerful for this sort of thing - LOL)
I apologize for not following up on the Oct 1 no-find. I had asked someone to go up and look, then the very next day I got a "find" notification, and I didn't notice that it was a backdated find (oops), and I assumed the cache had been found and told my local maintenance contact not to bother with the trip.
