Looks like good cow country. I've not much travel experience in Wyoming and that looks better the country I saw coming up by Thermopolis and over to Sheridan
Thats what I wondered, it looks like the best way to insulate a pole building.
There is a building near me that I see just did it and I haven't been able to talk to the owner yet to see how he likes it.
Great pics of beautiful country and family, welcome to the forum. We did spray foam in an old train station we restored as a store, and loved the results. Amazing insulative value and acoustics for jam sessions!
