Here's an odd one for ya... My driver's seat keeps creeping lower on me. I like to crank it all the way up as far as it will go. I'm a bit on the short side, so it's easier for me to reach the pedals that way. Over the course of a week or so, I notice that it gets incrimentally more difficult to reach those pedals. I check on the seat height, and I discover that there is  a lot of up-cranking to get it back up to the highest position.

Anybody else notice that sinking feeling?

Actually I haven't at all. I like mine on the floor. Just the other day I realized mine was still up in the air ever since bob re-adjusted it during the vegas trip.
