The summer-crowded waterways aren't attractive either. Why was it out of the question to move the race to October? You'd get wind, cheaper lodging rates, and fewer people crowding the waterways...
Tami,
I think the reason the date was moved to June was to get better wind conditions. The sea breeze is typically lighter in October if it shows up and sometimes a stalled or weak cold front makes for a long race. The seabreeze is stronger in June.
See ya at Horn Island Hop!
