Sorry to hear you were separated more then once during the ride. I hope you still found enjoyment riding the wild terrain of Pittsburgh's metropolitan area. Keen observation on the road markings, you are correct, they are indications of various Pedal Pittsburgh routes. This was all by coincidence, it happened this way because our route took us through 8 of Pittsburgh's well known parks.
When we were finalizing our route in August we unknowingly road the morning of the event and received a lot of envious looks on the big hills but an overall feeling of solidarity to the pedal!
Thanks for coming out, hope to see you at the next Rally.
