A coworker of mine, Eric (aka. Sir_Zman on Dodgeball), got some TV time in a story about geocaching in local parks on KARE-11. He’s around 2/3 the way into the video counting. You hear him before you see him.
I haven’t tried it yet, but should get out there and give it a try one of these days. I can tell you this for sure: a few of us could have used GPS units when we got lost in Murphy Hanrehan Park in Burnsville on Saturday morning in the rain.
