Re: NJ boater looking to use boat in NY lakes....
+ 1 on the envasive species. Often there are DEC officials at the state ramps checking your boat over for coast guard regulations and your boats cleanliness. I wash my hull on a weekly basis so they've never bothered me, but on some of the adirondack chain lakes will ask the last body of water your boat was on and can deny you access if your boat isn't clean. Milfoil, water chesnut and zebra mussels are the biggies.
Skaneatleas lake is a hard finger lake to launch on. Only one state launch with maybe parking for 20 at most. Lake residents dislike outsiders on their lake, only other launch is a BIG pain in the *** and parking is a 1/4 mile away at the fire department.
