Droid Users in Utah?

[The Zune Lune]

So, I am sure there are those who will start reading this and think, "Why is this quesiton posted here, it doesn't belong here", but hear me out, it actually does.

I am planning a trip out west this summer and will spend several days in Arches, Bryce Canyon, Zion, and the North Rim of the Grand Canyon. Looking at the VZ 3G coverage map, things look spotty. I know spotty coverage can really drain your battery. Any Droid users in Utah (or other similar locations) that can give me tips on how not to drain my Droid in 4 hours while I am there? Also, any ideas of how coverage is in Moab and Kanab? Are there any apps that will turn off services autmatically in these types of areas?

BTW - there is a National Park app that has all of the maps for National PArks - very nice.
