But you did label it properly and I *think* I did the conversion properly.

30 Celsius * 9/5 + 32 = 86 Fahrenheit.  (low end of range)
40 Celsius * 9/5 + 32 = 104 Fahrenheit. (high end of range)

Maybe it's just my lack of experience with damp coal, but .... ???

Apologies once again, practically every point I made had already been 
covered by one or more of the other lumen-aries on the list ;-). I 
think I'm going to have to turn off digest mode, I'm repeating you 
guys too often. Too often. Too often....
