Finally found the parking passes, $30 for 3 day M/C parking, $60 for 3 day cage parking.
I had to log in, then add tickets to my cart, then continue shopping. After all that parking passes show up on the events page.
M/C parking only is lot J on the outside of turn 11. Hope that's large enough?
Total 3 day GA pass with M/C parking $128, not too bad it seems. Just a little bit more than a 4 hour Supercross with parking at Cowboy Stadium.
Now to reserve some lucky relative's spare bedroom for at least 3 nights.
Wonder if they are going to inspect my cases to see if I'm carrying my lunch in?
