[Sketching17] Update #1 date correction: charrette is 7/31-8/2

[Mike Kuniavsky]

Hi. A quick correction: the charrette is July 31-August 2 (I had typed 
August 1).

Also, because of travel schedules, I expect we'll start winding down 
mid-afternoon on August 2 to let people make their evening flights from 
from Detroit Metro.
