Delorm has the contract for USGS maps on DVDs. I bought the US set. For My state Wildfower Productutions did the USGS maps on CD and sold out to Delorm. Your county ORV office alsl produces a good scale map and you may need it anyway as in some jurisdictions federal agencies set waht roads can be traveled and those roads are printed on the ORV map so if you are driving on a road printed on the ORV map you are driving in a non closed area.
State Atlas and Gazets are not bad. Ther is also a map series called Green Trails.
You can also use Google Earth and Map Quest.
