I love geocaching in Texas parks: they all have multiple caches, the traffic is pretty high so there is good turnover in trackables, and they use large ammo boxes as caches that are a piece of cake to locate.
With GPS, you get led to the site. Here’s what my iPhone looked like as Penny and I zeroed in on the site.
As expected, the cannister was easily found with my "truffle hound" helping me out.
I signed the log and saw that among all the items folks had left in the container (essentially junk like lucky coins and magic rings) that the was a trackable item with a metal tag attached.
Each trackable has a unique code that identifies it and allows the owner, and others like me, to observe the activity. I reported that I had taken the item so it now shows in my inventory.
In looking up the number, I saw that Princess Ariel was launched in Vancouver in 2010 but as you can see from the chart, sort of got lost in Texas. (Probably stashed away in someone vehicle and forgotten.)
So, I plan to lug her back to Vermont, probably visiting a few caches along the way, and place her in an active cache where someone can find her and move her along. I think she needs to explore New England.
