Looks like skies will be OK in an hour or so (now 8:48 pm) in Rochester. Not much wind but the humidity is high and the temp is forecast to be dropping and so might not be the best seeing conditions. I'll take a look at Jupiter and Saturn in 30 minutes or so to get an idea. If you do go to the Pine Island site let me know; otherwise I'll be staying at my home observing site (which is not quite a dark sky site) but you are welcome to come over.
