Sounds great, enjoy your hunt in CO. I have the DeLorme Topo USA series resident on my laptop and run off maps as I need them for a specific area. The services you describe are great when you want that kind of detail for a larger area than your home printer can provide and are really cost effective. If you wouls like to see aerial photographs of the area you are going to hunt, got to www.mapquest .com and use the advanced features to type in a LAT/LON of the area and zoom in.
Have fun!!!
