Eric rode to my house where we followed Bonifant, Bryants Nursery, Briggs Chaney to Old Columbia Pike. Just before we got to MD-198, we turned onto Tolson to Blackburn to take the sidepath trails to MD-198 on the east side of its intersection with US-29. We then turned onto Cedar Tree, then Bentley Park to the start of Konterra.
We rode Konterra all the way to its end at MD-212 (Virginia Manor / Ammendale Rd). From MD-212, we went all the way to Old Gunpowder / Powder Mill, turned left onto Powder Mill and then went straight onto Montgomery (instead of heading down the closed side road toward White Oak). We followed Montgomery all the way to its end at US-1 (Baltimore Ave) where we went through that silly-ass left/right to go down Rhode Island Ave. We took R.I. Ave to the R.I. Trolley Trail toward College Park.
We got off the R.I. Trolley Trail and rode Knox St over to Baltimore Ave for lunch.
The rest of the route back to home is very standard.
