The wife and I have driven through that part of Wyoming five times in the last ten years. One time we were with her sister and bro-in-law in a fully loaded minivan. The crosswind on I-25 was so strong I could barely keep the van on the road. We stopped at a tourist info station in a small town, and I remarked on the strength of the wind to a friendly guy behind the info counter. He told me the wind usually blows stronger than that.
That definitely is Wyoming. We just had a horrible wind storm last week. 60 mph gusts at our place, 70 + mph along I-25. They had to close the hiwy just west of us because of blowing dirt...a dirt blizzard. Can’t imagine what it would have been like in the 30’s. to go through that weekly, yearly.
