BOTH

All of the above b/c you never know if something will go wrong with the GPS.  It's an electronic piece of eguipment that will possible fail.

I don't have either, but wouldn't mind at all if I did have a GPS. I'm usually going to the same areas I have for years, so know them pretty well and what I'm going to do, where dirt roads go etc. There have been a couple times though out in the desert where it all looks the same and started to get nervous where to find my truck again... would have been handy, LOL.

Both  you can never be over prepaired!!

 I have both, I agree that something can go wrong with the electronic device, batteries always  die when you don’t have any spares or are using the spares.  You must keep up your skill with a map and compass and know how far you have traveled,, has your pace count changed over the last couple of  years?
