Morning mist, drizzle, fog, & wet roads CANCELS 9/26/2023 Geist Pool ride.  I will reschedule to tomorrow (Wednesday) - see you then!

Likely rain across the route cancels the Summer's End Ride to Sticks for Saturday 9/23/23.  Ride will be rescheduled in October when we can still mark the end of global warming extended summer.

I changed 13/15 PA Flats 9/12/23 ride start to 9:30 am on the BBC Calendar

Change to 8:30am start time for the Wednesday 9/6/23 Lees Mill Loop from MWP.  A half hour earlier start will have us back before temps reach 90°F

Due to the Seminary Rd detour, the Lyons Wards route near end return (mile 31.7) was modified to take Marburg to Countrybrooke. The Seminary Rd surface is unstable likely due to water main failure.  I have updated rwgps 9/3/2023.  Please download a fresh course from rwgps (although Seminary is technically "rideable") from: https://ridewithgps.com/routes/42969038

By request I have revised the Chocolate Bunny route to add a stop at the Filling Station Cafe at mile 32.  If you downloaded Library cuesheet or the rwgps route, please do a re-download.  Distance and climbing are about the same.

...Why not start the ride between 10 and 11 am and end around 5 - 6 pm...

It is still summer, sun is still up early, and an early start beats midday heat and traffic.
My 2cents

Do you actually mean the Troyer Rd bridge rather than Harford Creamery?
Otherwise your detour route does not work.

Paul Coleianne has cancelled the Ocean City rides for 8/23 & 8/30 2023.
