Marc, have you ever watched the line of red lights leaving the fairgrounds after the fireworks? We have, from the comfy and airy ledges of the Millbrook trail, all the while sipping wine and laughing at the slobs inching their way down county route 7. It may not be NYC, but getting into and out of town that night Suuuucks!
Also, you can see the fireworks from New Paltz, Newburgh, Beacon, Poughkeepsie, Kingston, Saugerties, Middletown. all at the same time. Pretty amazing.
