Hi Ken,

I'm familiar with Alex Danko's work, but you've missed this point that
I made :-

"Many existing astronomy weather forecast sites use the same data, but
present information for
only 1 specified lat/lon point at a time."

That's just what Clear Sky Chart does - one lone, single point at a
time.

My charts let you see what conditions are heading your way, and if you
should drove
N,S,E or W to get to a good observing point.

Besides which, Danko's charts ain't much good outside North America.

Andrew
