Hello. Getting ready for another adventure in a month or so, my first with my brand new GPSMAP 60cs. Looking at Oregon, NoCal, Nev, Utah, Idaho and Wash. So what map software do you use? I'm currently looking at US Topo, US Topo 24k Nat. Parks, and one or two on e-bay without the garmin name. Any sugestions? For example, something with the Lost Coast Usal road and King Peak road, and the Death Valley maps of roads like the Steel Pass and Teakettle junction.The US Topo24k West sounds good, but is more expensive than the three disk US Topo covering the entire USA. Whats the diference in detail, and is it worth it? Thanx!
