Here's a freebee. IDK if this is available to everyone but here in NC I can go to the county website/ tax office and use their mapping software for free. It also allows zooming and the ADDED bonus - you can find out who owns it/ where they live/ how big the parcel is/ etc. From there I go to yellowpages.com and type in owners info, get the phone number and call to set up an appointment with them to discuss hunting their land. I have aquired some really nice properties, done some preliminary scouting and never left the computer.
