Well, you can get to McDermitt on Highway 95. There is a Texaco station on the Nevada side of the OR/NV border. It's about 180 miles from Boise, which is the nearest larger city. Or 75 miles north of Winnemucca, off of I-80.
Then, you'd fuel up, and head east. Refer to topographical maps to pick your route, carry extra fuel and survival supplies for several days, and remember that some roads are subject to blockage by snow until the summer.
It's a vast and desolate landscape that makes for a good escape from the city.
