Sigh. I cancelled my summer & fall trips volunteer gigs in Louisiana and New Mexico. My decision involved a combination of math (5,600 miles รท 7 mpg x price of gas) and the fact that I want to stay close to my Big Little Dog's vet. She's the first one who has ever tried to take a comprehensive effort to help him. It's costing (gas!) $, but he's my buddy.
I am still going to San Juan Island (2,000 miles round trip), and re-upped for a volunteer stint at the state park where I camp-hosted last summer. THIS year, however, I'm going to find a sailboat so I can enjoy the water. Time to start checking craigslist.
Next year I want to just travel -- without time commitments -- if veterinary medicine permits.
