Pheasant Ridge is actually in Wilsonville. It is a lovely park, we stayed numerous times when we had children living in Portland. Quiet, very close to major shopping, you could walk, we didn't. There have been complaints that they are very strict with their rules...where to walk the dog, night noise, parking...I found this to be wonderful. I could easily follow the dog regs, nights were nice and quiet, and there was plenty of parking. If you stay there, and if you have time, one day exit to the right, keep right on the back roads, and you will come to one of the few small ferries left in the USA. (operated by the State as a historical landmark). Or you can exit right then go left at the fork and take back roads all the way to Portland. A beautiful half day drive.
Anyway, it was a nice park.
