Bumping this thread - the wife and I are planning on riding from New Glarus to Madison and back on Saturday using the Badger State Trail. Anybody know what the conditions are currently like? I'm on my touring bike with wide tires so I'm not worried about much, but my wife will be on her road bike with 700x23 slick tires. She's a lightweight so it may not matter, but does anybody think she'll need wider tires to enjoy herself?
