Integrating Technology Into a Long Trip?
xsalmon asks: "I am about to undergo a long trip around the continental United States, via hiking/cycling/walking and other self-propelled means of transportation, to raise money toward AIDS/HIV research. What kind of utilities/devices would you bring to increase safety/security? I'll be hauling enough in my backpack as-is, so any suggestions would have to be lightweight and portable enough. Any ideas?"
and your "HIV/AIDS" T-shirt should both help to scare off muggers.
Seriously, though, the handheld GPS > the PDA with GPS. My PDA with GPS could never handle the elements.
When I've done long hikes, I actually carried an old car inflatable tube tire and a mini CO2 canister. You can inflate the tube in an instant (about 12 inflations per 6 pack of CO2 cartridges) and float down the river. I'm lazy.
The CO2 cartridges also come in handy if you want to cool down, just remove the inflation adapter and am at your chest -- instant cool down.
I always bring along an extra few pairs of socks, too, they can get pretty grotty if you forget extra sets. And lots of protein and fat packed bacon is my friend on long hikes.
