I FOUND YOUR TRACKABLE! (in GC7FHF6 in Attleboro, MA) And it looks in perfect condition too!
Here is photo proof! https://photos.app.goo.gl/EHGp9wvpRn8u7hhj8
After reading through the TB Goal, I think that is a unique. Lots of little fishing spots around here, not sure how many of them are actually good, since I don't fish too much (at least not recently), but we will get this guy back on the map soon, near a great fishing spot!
I'm happy to have found this and hopefully that made your day! I wonder where it has been for more than 4 years... it's a shame that people don't log these, or just steal them. It is a cool fishing lure hanging off of the dog tag! All the way from Franklin, MA to Attleboro, MA over 4 years, and not a single log. That just amazes me.
