Edinburgh's critical mass Edit
Edinburgh's critical mass is held, like most others, on the last friday of every month. everyone will meet at the bottom of the mound next to the national gallery of scotland between 5:30pm and 6:00pm. After about 1 or 2 hours of riding, it always ends at the peartree, a local pub, you can tell when the end is near because you will hear shouts of "TO THE PEARTREE!" from many people. once there the over 18s (there are a few people who go along who are younger) will have a pint, or 4, and then try and cycle home.
