Thousands of pro and amateur BMX racers from all over the world will converge at South Park BMX in Bethel Park this weekend for the Stars and Stripes Nationals. And one racer in particular might have a bit of an advantage over the rest of the field. Cameron Bramer, 19, South Park, grew up five minutes from the track and has raced on it for as long as he can remember. Bramer, one of the top riders in the country on the USA BMX circuit in the 17-20 age group, will compete in races Friday through Sunday in the Expert Class as well as the Cruiser class. He expects to come out on top on his home course.
