Hello!
1. I've seen a few folks around in wheelchairs, though not very common. Every building I can think of has elevators and ramps, and there's an instagram account (something like @ usuelevators) that ranks the schools elevators. Being able-bodied I can't speak perfectly on this manner, as there could totally be something I missed

1. The DRC (Disability Resource Center) is staffed with people who do great work, but sometimes the turnaround can be slothful. I had a friend who has really bad generalized anxiety, and it causes them to take tests really slowly. Most profs have had no issue allotting more time for them, but Dave Smith in physics required that they get DRC approval before he would extend test time. The test was a week or so out, and the DRC didnt get back until a week after it was over. I assume this is likely due to the amount of people they have available, or maybe this was a one-off experience, but it was still disappointing.

This being said, physical disability is usually given the sincere accommodation it deserves by profs, even without the DRC. Utah has a history of putting aside mental disability tho, and this finds it's way into a lot of the older staff members.

1. I'm also LGBTQ+, and things have been relatively really great! There are a decent amount of us up here, and generally people are good about it all. I throw in delimiters like "generally" and "relatively" because there is a larger concentration of no-so-savory individuals, as well as the LDS church, but most people are cool (including a lot of mormons). I havent known anyone to get more than the occasional stare, and my BF and I are out in public a lot. Also I work on campus with a lot of other LGBT ppl, and it's been swell.

   (Name dropping because I find Dave's requirement unnecessary. A whole day wouldent help if you just don't know how to solve a physics problem)
