I didn't say I don't believe there are NO places, it is just hard for me to imagine that when you see the bay thinking it is only 2 feet deep.
I was really shocked a couple years back to learn that Klamath Lake was not very deep either. When you drive by these places they appear to be Big and Deep.
IMO, it is IMPORTANT not to play down the 2 foot depth point, because (again, IMHO) the way SP disposed of Laci and Connor is as follows.
He took the boat into shallow water, got out, lifted Laci out, then towed her into deeper water with weights attached wherein he cut her loose.
To me, unless there is evidence to rule it out, this is an obvious explanation for the disposal method AND the reason why Snott washed his clothes as soon as he got home.
