I would like to say upfront that the search option here has helped me a great deal. When I was curious as to what everyone carried for first aid I found a "thread" ( I believe that is what they are called ) which answered most of my questions. I would like to know however, what items you did not take with you, that at one time or another you wished you had.
I searched compasses and found a thread debating compass vs GPS and after reading 2 pages my head was spinning so bad I got lost in my own house for 3 days.
I have waterproof maps of Yellowstone and I intend to get a GPS and will hopefully be very familiar with using it. I still think I need to get a compass. Are they not all the same? I found a place online which attempted to teach me how to use one but I have a funny feeling it was the same nice old lady who tried to teach me algebra.
Any advice on what to buy and how to go about learning to use it would be much appreciated.
