For me, I don't think that gas prices will have a big effect on my travel plans. My little Saturn gets nearly 40 mpg on the highway, and the only big trip that I usually take in the summer is going home to see my folks. The price of gas could make the trip a little more expensive, but I make a good living and live carefully. I can afford to pay a little more for that trip.
A more interesting question for me will be whether I'm up to kayaking this summer. The truck that I use to carry the kayak doesn't get good mileage, but I just didn't have much energy or incentive to try kayaking last summer. If I'm still lacking energy this summer, then the price of gas will be irrelevant. If I feel more like doing things, I might end up doing more trips that are closer to home than I would if gas were cheap.

I’m a poor nursing student ... but can afford the gas. I would have to sleep on the ground where ever I landed though! *ha*
