Chicago Exit Ride
Bike ride from Rogers Park to Union Station to Vernon Hills in clear but frosty early winter Chicago weather. Mostly on the lakefront path. About 75 minutes riding speeded up x30 for a quick two and a half minutes.
L.A.T.E. Ride (audit)
Long video attached of them just coming and coming... Possibly Chicago's second or third largest group ride (after BtD and BLT); several times larger than Critical Mass.
