Great post, technically and artistically.

It's a well known condition in my part of the world. Several Universities are known to have a huge home advantage. Colorado, Colorado State, New Mexico, UNReno and Northern Arizona among others. All are over 4000 feet.

Professional sports are affected too. The baseball flies better in Denver than anyplace. Football teams hate to go there. Hockey and Basketball also.

Interestingly (maybe only to me :) ) is that Phoenix is the second highest baseball football and hockey venues. My elevation is under 400 feet, and Phoenix is less than 200 miles of seemingly flat ground from here. Obviously it isn't flat.

Thanks for a great post.
