No particular disruption, either; apparently enough locals stayed home that traffic didn't get dense.
There seem to be road closures around the stadium (which makes sense), and it seems that Mountain View closed a segment of Central Expressway for traffic-control purposes, presumably to encourage the traffic to stay on the freeway.
No sign of the "security perimeter" aside from lots of helicopters, and the only black helicopter I managed to get a good look at bore the markings of a local TV station. So, "security perimeter" means "we'll have helicopters buzzing around over the general area"? And maybe there's a plan in place for intercepting terrorist blimps?
I dunno about the area within Provo-mortar range of the stadium, but I'm sitting within [example deleted] range of it, and in walking around this afternoon I didn't notice anything that would prevent someone driving in with [idea deleted]. Unless maybe DHS has magic dowsing wands.
Oh, well. No boom is good news, as is no traffic jam. Boom Would Not Add To Shareholder Value. And with these rich people coming in from all over and experiencing the early-February weather (currently 71 degrees brilliantly Fahrenheit in my yard), maybe some of them will decide they want to join the spring real-estate fight?
