In US the 2 popular formula spots couldn't be more different, San Fransisco and Miami,
one is high wind and popular because fleet is very competitive. In Miami now days almost
all regulars have formula board, mainly used for free rides and drag racing across the bay,
reason behind popularity is avg winds from 7-12 kn, it's just practical. But once people
get really dialled in, they realize how much FUN it is.
