Schedule of events, tickets, etc??

We leaving Atlanta early Thursday headed out to Chicago. I have looked over the site and searched for "schedule of events" and found nothing. Anyone have a link to the schedule of events for the whole weekend? Will there be anything going on at the track on Fri ( saw mention of pit bike race Sat. night)? If not, we may just show up Saturday morning.

Also, I assume since it is an outdoor race, you can buy tickets at the gate (outdoors do not sell out right)? Here locally what do you show up at the track affects your ticket price. Same for this race? Showing up for Thur. thru Sunday is significantly higher than Sunday only, will this be the same? Any reason to order tickets online? Are tickets really $120+ each for general admission (that's the amount shown on the example I saw)? I mean I am going regardless but dang that's steep.

I am super excited dammit. We went to the nationals there in 06 and 07 and had a blast but I expect this to be off the charts. Hard to work these last two night shifts. Ready to get this thing started!!

Thanks Guys,
