Here it goes:
I've mapped out this route for Thursday's ride:
This route is 15.12 miles to breakfast at the French Bee in Parkville. The return is about 25 miles for a total of 40. There are a multitude of "alternate routes" which could make the total mileage as short as 30 miles.
The French Bee cannot handle a big crowd so if a langer number of riders show it would be easy to redirect this to the Riverside Corner Cafe or even return to the Crackerbarrel (about 24 miles to breakfast - directly across I-29 from Embassy Suites). The northernmost loop could be ridden after breakfast for the 40 mile total (or not).
The latest forecast shows pretty good weather conditions with a increasing south wind.
