Maybe I should stick with the GPS.
At least I can do a point to point and find my way home even if I have no one to talk to.
Go back the same way you came
I'm assuming you don't have some big bad Jeep that is going to take you into uncharted teritory. Probably go to Waiparous, run the 2 trails, map them on your GPS. Then realize, hey, I don't need a computer gizmo to tell me I'm on trail 1 or 2, return it at Walmart for a full refund
Seriously, some people get so involved in the GPS they have no clue where they are, which way is which and get lost going to take a pee cause they don't have the GPS with them...
Get a map, compass & basic skills. Take note of where the sun is and where it is going. Which direction the water is flowing in the creeks, landmarks like mountains in the distance, bridges, funky trees, intersections, etc... That theory knowledge will help you more then the "signal lost" errors as you look at your GPS screen for an hour instead of getting out of the Jeep and looking at where your tire treads are coming from.
CB's are handy sometimes, it's too bad many internet social networking addicts have access to them and use them like they're at a party and can't stop talking
I bought a handheld CB at a pawn shop for $40, it's volume it usually turned right down, unless really needed.
You seem undecided, why not put the money away for now and go enjoy life, jeepin' , 4x4'ing, maybe read some magazines, talk to some people, etc... come back in a couple weeks or months and then you'll have your own clue where you might want to spend your own $.
