check this link out. i know a few guys at chicago mastercraft that set this up. Riding the river is super illegal not to mention its nasty.
Yeah we tow it down to Ottawa usually on the weekends because lake Michigan is crap for wakeboarding. Surfing the big lake is easy. We tow up and down oak street beach. Load up the bags and pile it with people. Makes a nasty surf wake plus at slow speeds it cuts right through the chop and makes a great surf. The bad ass walker board doesn't hurt either. It's a lot of fun out there when you can't wakeboard.
Ever ride down in Ottawa?
