Was anyone at the Canal around 5:00 on Saturday. I was heading home and could see thru the trees the superstructure of something pretty big heading thru toward the bay. It was out of sight by the time I got to the pull off and when I crossed the Bourne Bridge. What was it?

I was there Sunday and someone told me a Cruise Ship went through on Saturday.

It was me. I am huge!

Cruise ship.
I've seen it a few times entering from the east end.
You can see the water displacement from the ship as it passes (the "tide" rises and falls by as much as a foot)
It lights up the area pretty well, but luckily it doesn't affect the fishing much.

The World maybe

it was a cruise ship went right by me .

Nope,
It was me, I am bigger.
Later,
Rick
