I downloaded Colorado Topo 2011 and Trail Maps onto my PC and into BASECAMP.
I can open COTOPO11 and locate a desired point, when I open the Trail Maps it shows the trails overlaided over the COTOPO11, but it is not transparent. I must switch back and forth to see both. I thought the Trail Map was to be transparent. Anyone have this problem? Any ideas to solve this?

When I try to download the PA Topo map I get a warning "This program is not signed and may damage your computer." Has anyone encountered this problem before? Is it safe to bypass and continue download and open?
