first Saturday of every month until October (weather permitting) at the minneapolis motorplex located in Chanhassen, Minnesota near Prince's old recording studio. I've been to the June and the July one so far this year and they were amazing. i would strongly suggest coming if you have the time to. It starts at 8:00am (you can start rolling in as soon as 7:30am) and goes until noon. everything from honda's to bugatti's to ferraris to vws, bmw, and minis.
