I went up to Northport the other day which is on the northern side of Long Island. There are some nice spots by the water to sketch and paint, but once the "season" arrives you can't park there unless you are a resident. Crab Meadow is partly on the water and partly on an inlet and has several nice spots to sit and sketch. You just have to watch out for high tide, ticks, and poison ivy. I was sitting low down to sketch this...watching the water level carefully. lol
