Yeah, I do sometimes. Also do the Hudson River and Lake George.
I kept my first boat at Longpond Marine with Elliot and Denise for about 10 years. Now I keep it on the trailer because the children are grown and we don't boat as much. I put it in Greenwood for 3 weeks and had to clean the bottom to go to Lake George. Left it in the water at Lake George for 2 weeks and it was as clean as when it went in. Beautiful lake up there.
Haven't run into problems at Greenwood lately.
