There is a similar, let's call it "weather anomoly" over us at Stone Haven Observatory. On many, many stormy nights over the last 14 years, I have watched lightning and rain pound the mountains less than a mile from my house. They will then dissipate directly overhead, only to resume their violence on the mountain tops two miles to the north. The "city" of Maricopa will receive nearly double the rainfal we get in Hidden Valley. It's just something about (extremely) local conditions that can affect seeing. I for one have found Jeff's claims debatable, until I look at my own circumstances and experiences. The difference being, he has data that show his viewpoint, and I don't! :-) Steve and Rosie Dodder sdodder@xxxxxxxxxxx Visit my web site at http://www.stargazing.net/Astroman _________________________________________________________________ The average US Credit Score is 675.
