What is the cost for the grandstand seating?

Good question! Their website lists admission prices for special events as TBA. All admissions are general admission. Many people bring lawn chairs and place them between the rows, or, even on the board or aluminum seat. I did that at the KISS race, and it worked for me. Biggest issue is that you face the sun, so act accordingly. The KISS race was $20, so I imagine the Amati will be that also.

Keith's post yesterday gave the information concerning the Amati Classic.
