We now might have to just use the Evergreen Air and Space Museum [sprucegoose.org] for an excuse. They recently have opened the "Space" portion up and we have yet to see it..........
Grants Pass, Oregon
It's fun to visit, but the whole thing is setup to be a museum to accomodate a space shuttle when they are retired, which isn't there yet.
It is still worth the trip, and the cafe on the space portion has great food.
