  Yep, I've practice that technique when hiking in the wilds and when 
hunting in unknown regions. It's helped me return to my camp/car more 
than once. These days I still practice it but also carry a compass and 
GPS, just in case. ;-)   BTW, the old trick of reading moss around the 
base of trees to locate north on overcast days isn't all that reliable. 
Moss grows everywhere! =-O
