Same here. 86 for a high after a low of 40 and already down to 61. But I still keep the AC on all the time - it just switches on when needed. Too lazy to open and close windows... (I know, that's sad)
Logs do seem to hold an insane amount of heat. Not a bad thing in our climate. I'm trying to grow tomatoes next to a South facing log wall, maybe I'll get something this time!
We can't really grow tomatoes here, but my new house has a wall of dark logs facing south under an awning that could be a great microclimate so I'm trying to see what happens. These 16" logs retain a tremendous amount of heat
