Cool weather experience

That would be a tuning nightmare in the 1/4 mile if the temperature changed that much from one end of the track to the other........lol
Here in Lethbridge, it was - 18c when i got to work around 7 am and warmed up to +6c when i went home at around 4 pm on Thursday.
For you Americans that was 0 F to +40 F in about 9 hours!
And if you can believe this, no wind to speak of..........
