While Grand Forks BMX's season started May 7, the energy for the second official race day on May 15 was just as cheerful as riders as young as two years to teenagers brought their bikes to the track in City Park for another evening of flying and banking around the course as friends and parents cheered them on. Races happen every Wednesday, with practice at 5:30 p.m. and races at 6:30 p.m.
