That's the correct attitude in my book!
Interesting notes on the weather thing. I believe that we should more and more push the mindset that show up and sail with what you got instead of choosing to stay away form the venue based on the forecast. Even with today's great weather, it's still often wrong or does not capture the full picture.
Case in point - this past weekend at the CRAC/WRCRA lighthouse Race. If you believed the NOAA forecast in the morning, you would have thought about whether you wanted to go distance racing in 5-10 wind. People may have stayed away based on that forecast. Why bother? It's light air, don't feel like drifting all day. If people did that, they missed out on a day of high teens to twenties, and a great romp across the Bay and back. Works the other way too - forecasted nuclear conditions may not develop.
Plan to race, show up unless the hurricane hits that day, and make your decision to sail based on what you see at the venue. At the least you get a road trip out of it...
