National Park System units in 49 states in 2022?

Since we're going to Alaska this year, and will be picking up a lot of national parks along the way, I'm thinking about trying to get at least one unit in each of 49 states plus the District of Columbia this year.

I framed up several routes that will allow me to do that I just need to join them and figure out how to get them scheduled. It's quite a bit of riding, but I've picked out parks that I've wanted to go to for a long time.

So, if I can pull it off, I'll get a couple things done I'll get a bunch of more counties, I'll get a few national parks that I haven't been to before, and I'll get some great riding in.
