It has never much appealed to me. I went to the 2004 one in Cernay and the rides were OK, but the peripheral hoo-hah I found strained and boring, and shot through with self-admiration on the part of the FFCT. Maybe it helps to get half-pissed every evening.
It still annoys me, because few local clubs will organise events while the SF is on. Still, we usually do a permanent then, which is always fun.
