I would like to know where I can purchase hard copies of topo maps? I would specifically like to purchase CO GMU'S 21 22. Any help in how to track these down would be appreciated!

Try USGS at 1-800-USA-MAPS, or 1-800-HELP-MAP or,

If you have a local BLM office, many times they sell Topo maps. Best bet: there's a book called the Colorado Gazetteer & Atlas (I think) printed by DeLorme (try a big book store). It is a series of atlas' that have topo's of the entire state.
Maybe try topozone.com.

I went to a office max store with my mapsand had them laminated. now I can use dry eraser markers on them. andI canmark hot spots andthe area I will be hunting in for the rest of the group to find me if needed.
