If you've ever driven north on I-5 through Oregon and passed Salem, you would have passed the turnoff for Silverton. When I turned off the freeway in Salem, I passed a large shopping area several blocks long with just about every store and bank imaginable. There is a Wal-Mart too, with a small lot. However, Lucy would not fit in the parking lots so I kept driving to the RV park.
The Silver Spur RV Park was literally built from the fields surrounding it: http://www.silverspurrvpark.com/index.htm. And if you have Happy Camper or Passport America, it's half price. The spaces are long, wide, have 30- and 50-amp connections, cable TV and free wi-fi. There are tent sites as well. The young couple who manage it are doing it right and I recommend stopping here if you want a quiet respite from the road.
The local farms have produce for sale like tomatoes, corn, squash and fruit. It's a vegetarian's idea of heaven. Three blocks away is the Oregon Garden.
I'll be here enjoying the area for five days.
