Rides in Irwin / North Huntingdon
I'm not quite sure if anyone lives in the eastern suburbs, but I wanted to let everyone know that I'm a part of a group that is riding from Irwin on Wednesday's a 6pm and some Sundays. We've grown recently and actually split into two groups: a carbon-road-bike-spandex crew and a somewhat slower road bike to mountain bike crew.
Let me know if you want more details.
