Also, everyone along the motorcade has been advised through the media to NOT be on their balconies (high rises), not be out in the front yard or on the porch, not to look at their windows or get on rooftops. Sounds like Moquetezuma passing through town (You could not look at him, you could not touch him, you could not turn your back on him - that leaves only bowing down very low to the ground.)
I was there a couple weeks ago to see my sisters bands gig. Traffic was pretty bad Fri afternoon but we had a blast. 50 to 80% chance of rain today. Austin will come to a standstill this afternoon once the Presidents motorcade winds thru town.
