I've been doing pop-up trailer "camping" (getting out of the house) for years, but I just got one in order to start taking out the family - wife, daughter age 8, and son age 6. I'm looking to go to a place with the following criteria as best as possible: 1) Fun outdoorsy stuff to do for the kids and wife (lake/stream/ocean, hiking, woodsy, etc), 2) Easy to set up a pop-up trailer, 3) Not too many surrounding campsites (eg Lake Kecheless and its 100 campsites is OUT) 4) Within an hour and a half or so drive from Seattle area. This is just to get into the camping thing before venturing out to further sites and scenes further away. Any suggestions? Thanks!
