Yeah, 2x that I haven't forgotten. One in 2004 I still remember I was layed over really low on my zx6r and I entered a piece of road that was shaded from trees over hanging on it. Well just so happens there was SAND...yes freaking sand out in the middle of nowhere and my rear tire washed out and was beside me for a split second at 60-70mph and luckily I kept on the gas and it corrected itself. Once I was straightened out, I cruised really slow and just went home. I felt like that was my sign that I'm done for the day. 2nd one was like in 2006. Same thing, but different turn. Gravel, near same speed and it did it again. I went home after that..lol. I remember the years because that's how much those times freaked me out.
