This is short notice, but it's the first I heard about it.
There's a Bike Rodeo this Saturday, 5/14, 10am - 2pm at the Overland Park Shopping Center.
More details HERE.
Highly recommended, if you know kids who are of bike-riding age. (Do they also educate clueless teenagers and adults about the rules of the road??)
Since one of my biggest complaints is lack of any formal bike education, this sort of thing is VERY welcome! The police may not be the very most informed people about bicycle law, but there's a better chance of getting accurate info from them, than from a family member who's obviously clueless, and not very interested.
