First of all - if you are planning on coming to an event you should check the schedule pretty frequently. As with lots of events like this things get shifted around and times change. It is pretty common.
That said -
There was a mistake on the schedule saying we were going to be at both the University of Washington and at Evergreen Speedway on Friday. That, of course, is impossible as we have only one truck in Seattle. We will be at UW on Friday and Evergreen on Saturday. I'm sorry if anyone had made plans around that!
