"Q" is Quartzite AZ on I-10 and Hwy 95 not to far from the California boarder. I listed it mostly as a joke, I think it is the single largest gathering of RVs in the west. There is a big RV show in January along with a really big Gem and Mineral and Jewelry Show and about 100 swap meets.
One of the largest BLM camping areas too. 18,000 acres or there abouts. It is just a fun time with a lot of RVers and a huge number of Snowbirds.
Glad you like the list, it is what I could think of off the top of my head. Another NP in the East is Isle Royale. It is an island in Lake Superior.
Some years ago, an ice bridge formed and IIRC Elk migrated to the island. Bridge melted and herd increased. Ice bridge formed again and some wolves went to the island. It became sort of a Galapagos Island in a lake. Biologists have been studying for decades. Herd is now waning as are the wolves. Both may disappear soon.
