Gosh, you are right, cyberwolf! I went up on top of my house today to sweep off some straw and it was freezing up there! When I got back on the ground it was 90 degrees F again. Absolutely amazing. I majored in Aerospace Engineering way back in the 60's and all that temperature/altitude stuff hadn't been discovered yet, Thanks for the info!

Now, after all these decades of attempts I may be able to get an engine to run.
