I was being little sarcastic about why we leave the shells where we shuck them.I guess seeing all those oysters leave the beach and having never seen what looked like a place where so many shells having been harvested,then having the shells returned leaves me a little skeptical.I hope your right on that insight.I'll have to keep a better eye out for those types of signs.I'm curious.Do any of those oysters ever get sold,"in the shell"thus not making their way back to the beach.
I'm not intending to do more bashing with what I wrote.I apologize if it came out that way.Its just an observation on mine,and probably 1000s of other peoples part.Fortunately we have people like you to educate us on how those things are done.
