With its flat surface, wide shoulders and lack of parked cars, Columns Drive near Marietta draws dozens of cyclists on a nice day, including many who use the somewhat remote road as their training track, riding lap after lap up and down the 2 1/2 mile street. But angry residents who live along the road in upwards of million-dollar homes say the cyclists whip along the street three or more abreast, cutting off cars, robbing the roadway and scaring people even as they step out to check their mailbox.
