I went to the Tucson Convention Center (the TCC as it's known by Tucsonans) today to shoot photos of the 94.9 MIX-fm Baby Fair.  You can see those in a separate blog entry.
While I was there, I shot some photos of another event happening at the TCC:  The Southwest BMX convention.  It was a sight to see from the windows on the second floor overlooking the exhibit hall.  There were thousands of BMX bikes and tons of riders.  BMX has really grown into a popular sport.  Based on the number of youth, it's obviously popular with people in their teens.
Check out the sheer number of bikes as seen from above the exhibit hall:
