It's not Lake Michigan, its a Southern Chill Lake, not a northern race lake.
You will fit, but don't expect to zoom across the lake especially on peak days, you may just tie up with others and drink. Check on slips right away. Several nice places to eat.. I like Jokers for drinks and tunes at night.
By the way, from Naperville/DownsGrove long time ago.. Man that place has grown.
