Sorry you ended up doing the back and forth. In the end you were probably safe doing that - any number of issues could have come up, none the least could have been the disappearance of the boat had you anchored and left it alone near the launch!! Easy pickin's there!! I had some toys taken out of my boat there when I had docked it to run across to the porta-potties a couple summers ago!
Anyway - hour and 20 from Meredith to LI - WOW!!

OUCH! Now you see why we never come up on Biker weekend!
