Some years ago I bought Nat. Geographics Topo! program for Idaho. It has the entire set of USGS topo maps for the state. Since then a number of mapping sites have come online but I still find the Topo! maps to be most useful. I just print out the areas I think I'll need on ordinary 8.5x11 paper. It's not waterproof and needs to be kept in a ziplock bag, but it's quick and easy.
