No signature item yet. I'll have to think about it. I have a Garmin Venture I purchased on Amazon, and it works great. I WAS using it to keep from getting lost on my bike. I have a terrible sense of direction and it has saved me in unfamiliar territory several times.

I also think this is a useful classroom tool, (I teach math, but I can see it in upper elementary, geography, etc!) and now with the geocaching? I'll have to hide a cache of treats on the track and let my students use the GPS to find it.

And finally, IPOD CACHING?!?!?!?! I'm heading straight over to find out about this one. I picture myself in a few years riding a bike with dozens of electronic devices hanging from a specially made bright yellow vest.

By the way have you seen this? geogear T-shirt
