And it's all just a couple of hours from the Bay Area!
I don't know about you, but I wasted plenty of elementary school hours playing Oregon Trail.
Now, you can stay in a Conestoga wagon at Yosemite Pines RV Resort & Family Lodging (just off Highway 120, 2 hours and 15 minutes or so east of Livermore).
According to the reservations page, "These air-conditioned and heated wagons sleep 4/6 and are furnished with a king-size bed and 2 twin-size bunk beds. They include an under-counter refrigerator, microwave, coffee pot, bed linens and are convenient to the restroom and showers. (Please bring own towels). Each wagon includes a picnic table and barbecue/fire ring."
Looks like fun, right???
