Here are the FLorida laws: We _are_ allowed to ride two abreast, but not if it impedes traffic.
* A bicyclist who is not traveling at the same speed of other traffic must ride as close as practicable to the right-hand curb or edge of the roadway. A bicyclist may leave the right-most portion of the road in the following situations: when passing, making a left turn, to avoid road hazards, or when a lane is too narrow for a bicycle and a car to share safely.
* Persons riding bicycles upon a roadway shall not ride more than two abreast except on paths or parts of roadways set aside for the exclusive use of bicycles. Persons riding two abreast shall not impede traffic when traveling at less than the normal speed of traffic at the time and place and under the conditions existing, and shall ride within a single lane.
