Both of those are old ferry landings and that might be why they're not suitable for winter launching . Iv'e never tried to launch a boat there so I am just guessing.
Don't park on the right! Last 2 times my buddy did, he chased off a guy who was looking in his vehicle and the next time he had window busted out and everything stolen. No one really uses that side to put in b/c of the breakins.
