Keith, you amaze me -- you spelled it correctly!
I suppose that you'll remember to take a pair of static readings -- one
for you, the driver, one for Tonya. I think you weigh a couple of

PS Don't forget, everybody, to plan on visiting the "Salt Talks"
get-together at the bend in the road on Sunday evening at Speedweek.
Nancy and I are bringing lots of pasties as well as other stuff, too.
PPS If you weren't there last year, and you don't know what pasties are
-- you're in for quite a surprise!
