I had the same problem for the eclipse. Interestingly, I was able to grab cancellations much closer to the event! We did have to move once during the week we were there, but otherwise we had a great solar eclipse experience and a great family reunion as well.

I did read about the problems with the Oregon wilderness areas. I was really miffed about it even though by the time it took effect my "hiking" has become limited to around the block with a walker. Old age has finally caught up with me.

One of the big problems with reservation.gov is that people make reservations and then neither show up nor cancel, leaving the space unusable while half a dozen cars are circling the campground looking for a vacancy.
