This is a mph vs. time (in minutes) for the 9.7 mile course.  Shoulda probably done it the other way around (minutes to mph), but it gets you close to your average if you didn't have a computer.  This is also a good way to gauge your computer's accuracy.  Mine was off by .7mph on the average.  If any of you hack some code for this, lemme know if I'm off.

You'll have to pardon the brevity of the report, we're about to go
pick blueberries, but I wanted to get this out there.

On a nearly perfect day to run a TT, we had a record turnout.  27
total people competed in today's event, two course records fell,
and all three categories have new series leaders.
