That what the 'suspension' is designed to do Mr Squirrel - you aren't
hurting anything.

...but you might get hurt if there are any locals around to object to the
dust you're raising. We have a lot of desert washboard dirt roads around
here, and btw they're not made by some funky contraption- they're smoothed
out by a funky contraption, but they're made by reg'lur 'ol driving.
Dust-ups (if you'll pardon the pun) from driving too fast on dirt roads
around here runs a close second to fights over water.
