Hi Steve, Don't worry or hurt yourself tryng to get it. If you do get a hold of the rope and the anchor is still stuck, attach a fender to it if you have a spare one and I will replace it, then we will have a fixed mooring at hand for when the "rangers" kick us off the pontoon.
I am away to mexico on monday for 2 weeks, I won't be online during that time but will catch up on the forums when I get back.
