I watched the Utah / USC game a couple of years ago from a box. Ran into Pres. Russell M. Nelson up there. The whole thing was a great experience.
Other than everything being red instead of blue and a little more facial hair, the experience was much like being in the LES loges. The people were of course largely incredibly successful (except for guests like me), polite, and frankly most active LDS people. Never heard any profanity or anything I wouldn't hear in a LES loge.
Now, down in the stadium, its a different experience. And don't even get me started on the MUSS. But when the people at the top of the U food chain say they don't personally experience ugly behavior at RES, the above is largely why.
