O.K., I like Marvin. But this is about bicycle happenings this weekend. The MS150 annual expo is Saturday from 8 a.m to 1 p.m. at Pembroke Hill, 400 W 51st St. Kansas City, Missouri. More racing in Lawrence with Spring Fling Criterium number five. The JCBC calendar shows the first of the areas ultra events, if you want to go long check out the brevets. And if you’re looking for something shorter, the Scooters Coffee ride rolls out at 8:30 from their location on Shawnee Mission Parkway.
