this was a cute and dangerous scenario...

cool cluster of kids on the capital crescent trail 
not sure where they are going
where they came from 
or how long they are traveling for 

no matter... it was a cool suburban summer scene

so these kids of various pre teen ages were rolling on the capital crescent trail
this one girl in the lead sprints off ahead
dismounts her scooter and then runs to the back of the pack to stop the last kid in the bicycle train
apparently she knows how to pedal but does not know how to break

it was a serious little rascals\fat albert and the gang moment
