First , some new car pictures : I went to the Obama rally today in downtown Minneapolis ( scheduled at the same time as a nearby McCain / Palin campaign stop ) . I got a free sign and a button upon my arrival . The crowd was just starting to trickle in when I arrived but soon the plaza filled up -- estimates were at 3500 people .
