TomD pointed us to where they have free maps to use in GPS units.

They also have info on using these maps with Garmin's "Basecamp" , which you can get for free here:

Basecamp Software

You can use these together to create and print very nice maps even if you don't have a GPS. You can use them on either a PC or Mac too.

They have Road maps and Topo maps, some with 20ft elevation lines, and maps that show Trails and Public Land Boundaries and more.
