I think the Natural History Museum has the idea. Also you could Uber or Lyft from a KOA if you're staying the night there. They have a light rail system, but it didn't extend to the Museum at the time. Worth the extra effort. It's an amazing place!
There's a street called Colorow just down the hill from us. You can park there.
The parking lot is pretty big. Maybe call and ask them?
I remember the parking lot being tight, I didn't see a spot for motor homes.
