Thanks guys!
Please keep in mind that those lines in space are merely approximations to reality. There is no place from Cajon Pass to Heaps Peak that I haven’t had close encounters with inbound commercial jets and other assorted fixed and rotary wing aircraft heading to Ontario, San Benardino, Redlands, March ARB, etc. Altitudes were treetop to 10K. My point is we need 360° awareness at a reasonable interval. (Nate may be working on an omniview periscope to compliment his belayer’s prisms). And then there’s fire season which can really add some head-turning. A higher level subscription to flightaware24 can yield 3-years worth of KML files into any local airport which could give a better idea of reality.

And never forget we get hind tits below Mother Sky!
