I can't even deal with the humidity anymore. I went out there last June to haul a car back and I about died, lol, and that's not even the most humid time of year. What always disappointed me living out there is that even during the summer I couldn't plan for car shows because you never knew what the weather was going to do that weekend, so pre-registering for anything was out of the question. It was always "wait till the night before and make a decision" type of thing. Always frustrated the family when making plans. That whole weather deal, both winter and summer, is what made us go west.
You're right though, our car events are spread thoughout the year and among 3-4 states since we have year round classic car weather, so it doesn't seem as "packed" on the calender. But we (both my wife and myself) can daily drive our classics year round out here
For me that's more fun than the shows.
