Crater Lake is a place that needs to be seen. The lake itself is like a gemstone, how it looks depends completely on the light. And it is pristine, no boats (well, there might still be a tour boat. I'm not sure). It is an amazing place for a fact.
Another nearly abandoned Forest Service Campground. No potable water, but good pit toilets and the campsite was wonderful. Plus Paulina, OR is the closest place, population 45. A general store/gas pump/tavern and one church in the place, I loved it. I can't find my pictures of Paulina. I don't know where I put them, I've been through every file from my trip. It's a shame.
Sounds like a great place. I know a lot of little towns like that in Michigan. I used to hang out in one of them all the time. Their little market has one of the best meat counters around. The bar had a good burger too.
I didn't try the burger, but I definitely liked the store keeper :)
