With a few notable exceptions (e.g. Dean Haskins and Orly Taitz come to mind) birthers are in the main homebodies, preferring to express their sentiment online rather than showing up at gatherings.
The amazing thing about this story is that it is a story at all. At the Florida Republican Presidential Debate, sponsored by CNN, a birther showed up in the form of a plane flying overhead towing a “Where’s the real birth certificate? WND.com” banner. Tampa Bay Online covered the pre-debate activity in its article: Dems, protesters and birther show up before debate. “Daddy, tell me more about the birther.”
