Re:Best ice cream places in New York (other than NYC) ?
Of places not already mentioned, I'd recommend the Snowman in the Lansingburgh section of Troy, NY. They make their own ice cream and have been in the same location for over 50 years. Great neon sign on top of the building, too. This was the ice cream I grew up on, and when I go back home, I'm delighted to find that nothing has changed.
I'd also recommend Gannon's in Syracuse. Again, excellent homemade ice cream with over 30 years of satisfied customers. The main location in the Valley neighborhood is usually quite crowded, so the Shady Brook location on McDonald Road just off Velasko is often the better bet.
