trinity blvd on the pasco/pinellas border... 2 miles of semi straight 4 lane road with no houses/street lights/businesses and no turnoffs or places for cops to hide... just go around 2-3am any night of the week and have someone else sit at the other end and make sure its clear. been about 160 in my friends dads car so you should be fine.
kinda far for you though
