There were a couple of flat rocks that people hit at low tide.
I tried to flop them over, but they were two heavy for me.
I would love to get a backhoe with an extendahoe in there
for an hour. It would help quite a bit.

Wouldn't that require a lot of paperwork and legwork to be legal? Those
rocks could be the key features to significant eco-systems!
