I have one data file that Catherine passed on to me as the "official" 
min/max file.  It has some extra calculation in it that I stripped away 
for the upload process, but no, nothing was a F to C conversion so I do 
not have the F values in a table.  I have found some F readings in the 
hard copies from the early 80's so they exist, but I would have to enter 
them again.

There were no decimal values giving in the F data that I scanned.  It 
just said "60"or "58".  I don't know what kind of thermometer they were 
working with back then.

I will, but I'll also print them out for Jeanne.  She is more 
knowledgeable than me on the weather docs.
