As a kid and teenager, hands down Rivertown. With The Beast, Kenton's Keelboats and The original Bat and as well so much more tree cover, it was my favorite area. Grown up me, enjoys enjoying a blue raspberry Icee along International Street and relaxing between rides. The spot behind Brewhouse is my other favorite to relax too.
IS for me. Nothing beats sitting by the fountains with a cold beverage and a meal/snack, kicking up my feet and taking it all in. As much as I love all the riding and fun, I've learned to appreciate slowing down and just taking in the moment. IS offers the perfect spot for just that.
