I just got off the phone with the good folks at Wilkey's Diner in Belle Rive. The restaurant is open for business and will be open on Saturday as riders pass through.
While Wilkey's is not an official checkpoint this year, I do highly recommend stopping in and having something to eat and refill your bottles for the trip down to Thompsonville.
These are very nice folks who run this restaurant, and are very accommodating to us crazy two wheel pedallers. Be kind to them and they will bend over backwards to encourage you to get back on your bike and down the road.
