By popular request - I'm adding a century for this ride. Here's a 100 miler that is flatter than flat - https://ridewithgps.com/routes/24176294 market at mile 18, 42 (maybe) 68, 79, are all I know - could be more - and there are several churches along the route where you may be able to get water. Post up if you're planning to ride the century - Biggs is looking for someone to ride with him.
