Contrary to popular belief, boats are actually much safer than cars, which inexplicably sink every time you drive them on water. Take a proper water road ride with today’s Groupon: for $7, you get a one-hour chartered boat rental for up to 10 people on Lake Glacier from Mill Creek MetroParks (a $15 value).

Sprawled out across 4,400 acres of public land and facilities, Mill Creek MetroParks attracts nearby humans with recreational activities such as boating and fishing. Rentals—which are available Wednesday–Friday from 12 p.m. to 5 p.m.—allow lounge-arounders to abandon dry land and its tendency to get dirt on everything by hopping aboard a boat with a ninesome of loved ones, then gliding off to explore 44 acres of steel-blue ripples surrounded by soothing emerald foliage. The nearby trails, gardens and Visitor & Education Center make it possible to extend the adventure even after the 60 minutes of floating are up.
