Come across this discussion A BIT LATE...
. Best thing u can all do is read a book i got in Cornwall last year called The Amazing Story of THE FLORAL DANCE. I can`t give details here (can I?) so e-mail me at coolpenguins@tiscali.co.uk and I`ll fill you in. I think this writer is the only guy who really knows what he`s talking about.
