Go to your county's website and locate their map section. All the counties I have done this with allow topo overlays on the aerial. Our county allows all the 8"x11" prints you want for free from your home PC. I got a 24"x36" aerial photo (photo paper) with topo overlays of the 1500 acreas we are hunting this year for the Michigan Longbow Association Hunt/Camp. It has been very useful for everyone who has come out so far. The 2'x3' map cost me $15 and after a hummus accident, it is now laminated. If I wanted to buy a 3'x4' aerial photo, it would have cost $20. Now those prices are if you go there and pick it up. If you want to do it from your PC, it is $7.50 shipping and handling.
