When we were there last year, we tried slipping our annual passes into the fast pass machines, and it didn't spit out a ticket. We tried two machines at Indy, and we saw other people successfully use those same machines. Are we just idiots and can't slide in the card correctly, or are we not able to use fast passes? It wasn't busy last November so we didn't try again, but we are now talking about making another trip this summer and can reuse the passes.
