No motor? No problem?  For two Tuesdays in August, race cars will not be permitted on the road course at Palm Beach International Raceway (PBIR).  Instead, the two-mile road course is open and available to non-motorized modes of transportation as the south Florida track hosts Two Wheel Tuesdays.  A different style of performance, power and speed will be the featured activity on August 23 as PBIR implements the motor-less events.  Cyclists, runners and rollerbladers will be the only modes of transportation allowed on the two-mile, 11-turn track.  Admission to Two Wheel Tuesdays is $5 per entry.  Gates open at 5pm and close at 9pm.
