A New Orleans second-line might not be inappropriate.
Glenn,This is from Wikipedia (yeah, I had to check, not being familiar etc.):"...participants walk and sometimes twirl a parasol or handkerchief in the air..."Sounds just about right to me. Probably more appropriate than my initial idea of "God hates fag-haters" protest.
Sorry to send you scurrying. I'm sure the mourners would not be the only ones twirling. Old man Phelps would probably be doing a little spinning on his own. It's people like him who foster a belief in God in the rest of us. Somebody's gotta give him a taste of what he's been dishing out.
