I just canceled a road trip to Tucson to spend the holiday weekend with some friends.

In my part of the world, gas prices are hovering around $3.70. And even though we've all gotten used to sticker shock at the pumps, I'm still reeling from the fact that it now costs more than $50 to fill my tank. Worse, $3.70 per gallon is low compared to prices in more remote stretches of New Mexico and Arizona.

The irony is that I could have gotten a round-trip plane ticket for about $90. Driving, however, would require me to fill the gas tank about four times, and set me back about $200.

And I can't quite justify the cost, even though I'd love to catch up with my friends and I'm extemely bummed to miss out on the spa visit we'd planned. So, instead of driving to another state for a luxurious pedicure, I'll walk to the no-frills joint near my house for a cheapy version. Hmm.

As it turns out, I'm not the only one rethinking their weekend plans. Some rock climbing buddies are forgoing a camping trip in a forest that's four hours away; instead, they'll stick to the mountains just outside town.

To my surprise, the majority of news stories on this topic, such as this one I found at Kansas.com, report that most Americans are not curtailing their weekend plans. Technically, the soaring gas prices should inspire people to become a bit greener, prompting us to walk, carpool, ride their bikes, or take the bus.

But I can't tell if that is actually happening. If a majority of people aren't scaling back on weekend road trips, how likely are they to change their day-to-day habits?

Personally, I've gotten a little greener as a result of the gas prices. I don't drive all that much, but I've noticed that I'm more inclined to walk or carpool whenever possible.

Still, cancelling this trip is the first major sacrifice I've made because of the rising prices. I'm not at all thrilled about it, there is a definite silver lining in knowing that I won't be responsible for putting some 1200 miles worth of carbon emissions in the air. It takes some of the sting out of the situation.

I'm curious to know what impact this is having on others. Have the gas prices caused you to reconsider plans for the long weekend? Are they prompting you and the people in your life to revise your everyday routines or try out various options, such as Car Free Tuesday? Tell us what you're doing. My credit card and I will appreciate any suggestions.
