I usually do a Kevin's day at the races for my customers as i live in the metro area , so i am at the gate to get in at 0500 to get close to the handicap parking when they open at 07:30 as i have a customer that need that parking facility , ,, if you arrive at noon count on a mile or so walk to the gate to get your tickets in ,
i would say leave a little earlier to get a little closer in parking , as 10 years ago for the first trip there , i got there at like 11:00 and was in row double N or section NN with2 youngsters and my wife ,,,,,,,
100 F on friday , and 95 on saturday ,, so coming down from Minn, p 94 to Madison to I39 south to La Salle to I 80 East is your best route to take , follow the signs when you exit onto rt 52 i think go south to the track.
Enjoy , it's a great facility
