My trainer & I also encountered wind this last week on I-80, going through Nebraska, heading tward Denver.
It must have been a storm front; just all at once, the wind began gusting.
This was the first time I ever expirenced this, and it was scary. I couldn't go any faster than 45mph, and it felt like I was going to blow off the road, a couple of times.
I myself was wondering what you do in a situation like this?
