Absolutely. I live in Washington state, and I feel like there's more nature in just this statethan I could take in over a lifetime. Driving across the state means going from a desert following the Columbia, through a shrub-steppe, into the Cascade foothills, up to the evergreen covered Cascade range, then down into the rainforests of the PNW, then on to the Pacific.
My wife and I moved to the Puget Sound area in 2009, and I've not regretted a single moment. We moved from the KCMO area and it's like night and day. People simply seem to care more about nature and outdoor activities than in MO. When we had a son, my parents moved out here to be nearby as he grows up (and watch him while we work); they don't regret a thing either, they love it here as well.
Even if you don't travel around going to the state and national parks, there's a ton of regional parks with trails, trails all over for biking and walking and a lot of nature all around.
I mean... it rains here all the time, and, and, earthquakes and volcanoes, it's probably a bad idea to move here. ;)
we did a PNW road trip a couple years ago and got lucky with great weather the whole time. Olympic National Park /Hurricane Ridge, Moss Forest, Mt Saint Helens, the coastal drive around Portland and Seattle are excellent.
I think I could spend a lifetime experiencing it.
