Sorry, no pets allowed. Service animals will be allowed as permitted by Federal Law.

Don’t drive. Be safe and take a cab, Uber, Lyft or the good ol’ Metra (BNSF Line). If YOU HAVE TO DRIVE, the Belmont Metra station has tons of parking available. Just a little stroll and you’ll be right at the entrance to our party. And for the environmentally conscious folk among you,who ride your bike everywhere, pedal your bicycle down to the festival and park that two-wheeled ride right along the fence. But be sure to bring your own bike lock! We will not be responsible for any damage or loss of property.

You must have the print-out of the tickets you purchase online or the barcode on your phone so our friends at the gate can beam you in. No reprinting capacities at the festival.
