459 I Street, NW
We have planned a special event for the season finale of our I Street Social Group Ride which has consistently drawn large numbers of participants over the course of the summer. This Thursday, come prepared for “The Cupcake Caper!” Foul play will be afoot, and we will need your help to solve a mystery. Whoever can solve the crime will win a beautiful Brooks saddle and matching handlebar grips. But this won’t be easy– you’ll have to closely follow the clues and piece together the evidence.
Participants are encouraged to come in costume and dress up their bikes– prizes will be awarded to the most creative. It’s Halloween, people!
As always, expect to ride a unique route through the city accompanied by tunes from our “music bike.” Bring plenty of cheer to animate passers by.
If you would like to attend this Murder Mystery Party On Wheels, kindly RSVP on Facebook.”
