I just saw the thread started by Weasel and Bunny (http://www.whiteblaze.net/forum/showthread.php?t=46300) about the cost of food for one month on the trail and one response got me thinking about how much money people bring on the trail.
When Jack Tarlin gave his response he summed it up saying, "So I'd plan on spending around seven hundred bucks, tho I'd certainly bring a bit extra." The way that is written you could infer that they should actually carry $700 on the trail.
As a noobie I was planning to do the same thing I do whenever I travel, carry a small amount of cash and plan on using a combo of credit card and ATM cash withdrawls in towns for resupply, gear and any lodging etc. Since the mid nineties this has worked for me wherever I've traveled anywhere around the world.
Do people really carry several hundred bucks in cash? Should I be concerned about not being able to use an ATM or credit card??
