A couple of weeks ago I was commuting on my trike in a storm, wind gusts of 35-40 mph the weather people said. I was doing all right, even though wind driven rain stung and I got soaked, that was no big deal. But I'd forgotten about the windblown SAND. I weathered it okay, but my trike's drivetrain got cranky (pardon the expression) and it took several cleaning sessions to get all the sand out... I'll not be doing that again if I can help it.
