Running the Delorme GPS & topo software, hooked into the laptop. It's cool because it's big, easy to see, etc.. but also pretty cumbersome. And I've been fairly disappointed with the accuracy of the topos.. like it doesn't see any road at Jenny Creek, just Rollins pass. Also my laptop battery only lasts about 5 minutes, so I've got to have my inverter on the whole time which makes my CB staticky. But that's a separate issue, obviously, though still why I don't use the laptop much any more.
Definitely interested in the October deal, hope to learn something!
