Warren,
You have a great location for temperature. Unfortunately I don't have that. It is either cold or very hot here. What do you mean it is all the way up tpo 56° today and no ride. You go when it is much cooler than that.
So far as the car being in the garage it gets hotter in there than in the carport. The carport lets air flow around it.
Tru is probably packing for the London trip. Hope everything goes great and he has a great time.
