Alternate *FREE* Topo Sites

Well, I've officially sent my nasty-gram to trails.com for their handling of the acquisition, and haven't yet received a response. In the mean time, I've found a couple alternate map sites from the forums on SummitPost. Some actually seem to be better in the short time I've had to play with them, but regardless, I'll take a free map over a $50 one any day.

Free Topographical Map Sites:
• ACME Mapper (http://mapper.acme.com) - The initial map pops up based on your IP address.
• LibreMap Project (http://www.libremap.org/) - Allows you to download TIF verisons of full USGS topo quads for free. Also includes other data formats.
• MyTopo (http://www.mytopo.com/maps.cfm) - A searchable topo / street / hybrid map site that includes Canada as well. Currently undergoing beta testing, but if you reply to the thread on SP (search for "Topozone is no longer useful", then the MyTopo folks will actually change the program based on your comments!
• National Geographic Topo Explorer (http://www.topo.com) - Currently undergoing beta testing.
• USGS Map Locator & Downloader (http://store.usgs.gov/locator/) - Allows you to download PDF versions of full USGS topo quads for free.

Damn the man & power to the people!!!
