Folks -- later this month I take off for a month long tour on the southern tier. This will be the longest single tour I've taken. My question relates to how much cash to take on tour. Obviously, I plan on using credit cards where possible, but I'm a little at a loss with exactly how much actual cash to take. Would you recommend minimizing the cash, since most places will more than likely take a credit card? Any assistance you experienced cycling tourists could provide would be appreciated.
