I downloaded the WABDR tracks from the Backcountry Discovery Routes web site into my PC. They are in zip files that Windows 7 can't seen to open and I wasn't able to find a way of loading them into BaseCamp. I ended up with some malware/fraudware while trying to find a program that would open the zip files assuming the files have to be opened to install into the BaseCamp program. A search on this site and a general Google Search hasn't gotten my anywhere. There must be something simple that I am missing since I couldn't find others who have posted on the same problem. This is for a Garmin Oregon with the 100K topo maps. I might spring for the 24k maps, has anyone who that has done the WABDR or similar used the 100K maps? Thanks for any help.
