On some roads, you just need to push through it. Siu and botto's picture are very common for all roads where I'm at. But at the same time, I've met with rougher. Once I vibrated (and I do mean that - very consistently bumpy) down about 3 miles worth of road. I don't have a picture of it (too bad Google doesn't either), but let's just say I won't be going that way any time soon.
