In addition to hunting I do a lot of backpacking in the offseason to stay in shape. I have found 2 products that meet all my map needs. I have NationalGeographic TOPO for Washington state on my computer. This allows me to print 7.5' USGS Maps for anywhere in the state, and also to transfer info as far as waypoints and tracks to my GPS. I also use Green Trails maps for certain areas. The 7.5' maps that I can print off are more detailed than the Green Trails, but I haven't had issues with either of them.
