A couple of thoughts: Utah Grand Prix was a blast being there. I'll give some things to MMP. On another site, there was talk of a lack of trees, grass, etc. Best things they've done (IMHO), shaded stands, and more restrooms than I've seen at any sporting facility. The hike from Parking Lot B kinda sucked, since walking was quicker than waiting for a tram, but if you got lucky, and the stars aligned, if you happened by a tram stop, and one was there, or close, they are quicker than the ones at Le Mans.
Also, pleasure meeting Messrs. Thawley and Dagys, and talking with them. Also, chatting with Mika Salo in the TSA line this morning at SLC airport (6:15am local).
