Topo Maps
(OP)
I'm searching for a site that would have topo maps online for FREE! I've found a s*&t load of sites where you can buy them but I've got to believe some topo nerd has indexed the entire topography of the U.S. one lonely Friday night.
If you know of such a site, or are the lonely topo nerd with the site, please let me know.

Natural Graphics has nation-wide digital elevation model coverage at a reasonable price. If you want DRGs, look at the state depts of nat resources or Geo dept. For instance, South Carolina has a great site. North Carolina has Nothing.

If you need to use these maps in bad weather there are two new brands of paper that will print waterproof maps even though the ink in your inkjet printer is not waterproof. One is called Adventure Paper from National Geographic and the other is called Weatherproof Paper from iGage. I saw a map printed on Adventure Paper that had been fully submerged for about three months with no degradation. The Weatherproof paper is almost as good. After several hours underwater there is what I would rate as 1 to 3 percent degradation of the printing but no running and it does not smear when wet. The paper from iGage is just under half the price of Adventure Paper and works in inkjets and laser printers. (Adventure paper only works in inkjets) It also comes in sizes up to 42x65. Adventure paper only comes in letter and 11x17. For construction projects in areas where the weather can be miserable a waterproof set of plans might be worth a few extra bucks. (11x17 Adventure Paper is about $2.00 a sheet Weatherproof is 96 cents a sheet for the same size.
