i've never been Geocaching...but that sure looks like the most micro cache you may ever come across!! cool!!
We are just not that good at Geocaching. It seems to take us too long to find the decent sized cache. We wound never have found that one. LOL. Congrats on a good find.
Yes found one of those the other week on a metal bridge in Glasgow........I did log online saying would the bridge be any less safe lol
