dumb question

ok, so I'm thinking of migrating south from New York. Where can I find
statistics that tell me where I can get the maximum sky (darkness and
clearness)? I am SO sick of New York skys and looking at sky events I can't
see month after miserable month. Does the Clear Sky Clock produce and kind
of statistical history? I know this seems a bit anal but I don't want to
pack up and find myself somewhere warmer but not as clear on average.

Thanks!
