Exceeded 32 mph drafting a bus. I had been meaning to try this for some time. I get off a commuter train at a transit center where several buses pick up rail passengers. Next time I will remember to be in the big chain ring, and hope to hit 40 before getting dropped. I think this bus tops out at about 45 (the speed limit) on this route.
