I just updated this scenery for MFSF2020. I am very impressed with it all. Most of all with the rising steam from fumaroles and hot pools. And of course old Faithfull going off. Not only that but the colder it is the more steam there is and the steam blows with the wind. I highly recommend this everyone else/ I cannot think of any other scenery where you can see so much dynamics going on. I will now have to get this for XP-12 too/
I have a couple suggestions / requests if you are doing more updates in the future. One is that at Old Faithful Lodge the parking lots are full of cars. But on the walkway around Old Faithful there is no one standing there. There should be a lot of people there watching. Another thing that would be great to see is herds of bison and maybe elk in the park.
