Yes, definitely, all roads are not smooth and one might need clearance for big rocks.
I did run over a rock and rip and hole in my gas tank a bit over a year ago. It was a schist stone I believe, volcanic and the same color of the road, hence only seeing it at the last moment. Very strange for it to have been in the middle of the road.
Problem today is that I'm still operating on Windows 7 and getting all of the warnings. Do I take them seriously? I don't like buying new when the one I've got seems to be working just fine. Going to do a backup today.
