Another #racing series that saw its debut at this week's #ALMS #Sebring12: the #USF2000 Series, with their #Mazda #MZR-powered #formula cars -- the same engine that's in our road-going #Mazdaspeed3, #CX7, #MX5, and more. Seen here is Neil Alberico, winner of the first of two races of the week in #Sebring.
