Theres probably a better way but this is what i did. I ordered a 'master' map that showed every quad (1;7500 scale) and name of quad in CO from USGS. From that master i was able to pick what quads i needed and ordered the basic paper maps.at the time it was 6or7 dollars per quad.I did this pre PC so i would think it would be fairly easy to get on the USGS web site and go from there.
I really like the delorme topo zone map program. I have been using it for years and is a good tool. yuu can create all kinds of maps. For the $100 i have the whole western united states. Than get the national geographic adventure paper so your maps don't run when rain hits them.
I also have the delorme topo usa and their hand held gps, they both work great. You can download aerials topos etc. onto both. Another option is mytopo.com, you can do a specific area that might run onto 4 or 5 usgs quads and put them onto one map,they can waterproof it and do different layering , they worked out for me in previous years also.
If you're like me and use a plastic tote to store your gear in then you might want to read further. When plastic totes are manufactured they are typically shipped with the lid on. This makes the inside of the tote smell like the plastic it's made of. To remove the plastic smell from the tote I use baking soda. I open the baking soda up and leave the box in the tote with the lid on for about a month to remove the plastic smell. I tried just leaving the lid off but I was still able to smell...
