I respectfully disagree with Cynic. Based on my experiences, there was quite a bit of O&D traffic besides my family on that route. I'm not an expert and don't know the exact numbers, but I'd say there is some value to the route when they did re-apply to serve it again. I hope it goes through, perhaps with a 170!
And ISP could be very well utilized and profitable if properly marketed. One of the main issues is the town of Islip has no clue how to operate and market it, with its proximity to NYC. HPN seems to do okay, perhaps they could learn something there.
