Summerfest might be more than 50 years old, but it still has a few tricks up its sleeve. This year, the festival has added attractions to keep fans entertained, cooled-off and well-fed.  Here is a glimpse at what’s new on water, on land and on wheels at the Summerfest grounds this year.  This year, Summerfest named the docks near the north end Summerfest Landing. Festival-goers can cool off on the waters of Lake Michigan with kayak, paddleboard and boat rides.  Last year, L.L. Bean offered paddleboard rentals in a pop-up shop, but this year it’s free (yes, free). All you need to do is sign up at L.L. Bean’s green tent. Don’t worry about having experience; instructors are standing by to help you navigate the waters. Rentals are on a first-come, first served basis and have been very popular, instructors say. The last round pulls away from the dock at 5 p.m.; on Wednesday, rentals were completely booked by early afternoon.  If you’d prefer to enjoy the lake without exerting yourself, you can take a free boat ride. Mercury...
