Crowds have filled Dealey Plaza in downtown Dallas throughout the day. They include media members, conspiracy theorists and tourists. Spotted in the crowd: a man playing bagpipes.
And Elvis has entered the plaza. A man impersonating Elvis Presley is playing his guitar -- and taking donations.
The plaza will be shut down soon as organizers prepare for Friday's midday ceremony that commemorates the 50th anniversary of President Kennedy's assassination.

Several roads in and near Dealey Plaza will be closed by Friday morning. Read about road closures and other details about Friday.
