Hehe, I can get lost on my way to my bathroom. A GPS is essential for someone who is directionally challenged like myself. I use a Garmin GPSMAP 60 CSx, great unit, although the Garmin maps are pricey. If you do decide to get a Garmin for nature photography in National Parks/Forests in the U.S.A., you might want to hold off on buying their 24k topological maps for National Parks. They sell them as 3 separate disks (East, Central, West regions) right now, or a 100K topo map of the entire U.S. Rumors are abounding that there will be an upgrade to make all their topo maps 24k in accuracy and come as a single product.
