Re: Windex vs. anemometer opinions...
I've never had fancy wind instruments, and sometimes not even a Windex if a fat bird decided he needed a place to sit!
Just go with a Windex. I'll just bet that you have a smartphone. If so, download the "WindAlert" app. It's free, and will tell you the wind direction and intensity from the windstations and NOAA bouys nearest to your location.
Here on the Chesapeake, there is cell coverage the whole length of the Bay.
