Eugene, a GPS is unaffected by cloud cover, rain, fog, snow, etc.
It is important that new GPS users understand this. The latest GPS units are very good at "locking onto" the satellites even in heavy forest cover.

I agree that, given the choice of a map and compass and a GPS, I would opt for the GPS, however I feel very secure in the woods with a good GPS, a 7 1/2 minute topo and a good compass. Using the GPS to obtain UTM readings and transferring them to the map using a UTM grid plate, will tell you where you are at any given time within just a few yards. Forget about longitude and latitude and learn UTM.

Frankly, I don't understand how anyone could not find North with a compass. Makes me think they shouldn't stray too far from home lest they never be seen again. Clue: to the compass challenged, they point North when held parallel to the ground.
