I'm bringing an electric tricycle this year. I'll lock it in camp and when I'm not riding it. Has anyone found a good and simple tool for GPS tracking of where you go plus something that can link into very very intermittent cellular signals or peer to peer networks at Burning Man? There are a zillion iPhone apps that can track GPS data, and a few that do dynamic peer to peer networks for text messages and such, but nothing that seems to combine those things.
I want to find something to 1) track how much I use the trike for battery operation and 2) find it on the playa if someone happens to steal it.... not that anyone would do such an awful thing, right?
