I'm plannig to travel in west USA (borrow a car, travel trough some camps, see the nature). Are there some good free tourist maps for android (or windows phone), or even jsut some reliable picture maps that i could download? Also any tips on stuff I shoudl not miss are welcome.
The US is pretty large. Is there a particular area you're going to be in, or will you be here long enough to drive thousands of miles? Where are you from? It doesn't do much good to recommend that you check out the mountains in Colorado/Wyoming/Montana if you're from Austria.
