Been in some tough wind. The toughest has always been in the desert. I have been in the Mojave when the winds moved from cross to headwind at a blink of the eye and Tumbleweads launched over our heads as it hit the small pitch next to the side of the road. I had ridden one stretch during a tour a half a dozen times and struggled mightily to maintain 7 mph only to find out that there was a slight downgrade and with no wind our group easily maintained 25 on the same road when there was no wind.
I have some rough days on the coast as well most notably on the 1 between Big Sur and SLO but it was more gusty and there were a few places to hide. The desert offers no breaks or places to hide
Coming across the Anza with a group of kids we have hit vicious winds I think four times somewhere in the 30mph range right in your teeth
