re: There is a BAD shark off of the NC coast

I agree, in part , to most of that.

Having been stationed in PCB for two years and then later logging 250 plus dives (most spearfishing) i know a little bit about sharks.
And while murky water and bait being present are factors in this , its also a set of conditions that is repeated each and every day somewhere in the GOF or Eastern shore between NC and Miami Beach.
Yet you hear about an occassional attack every couple of months.... Single atacks.
Here you are looking at 3 attacks , in 5 days, within a couple miles of each other.
Sure there are probably a couple hundred, maybe a 1,000 sharks in a stretch that size under the right conditions. Could be multiple sharks ... Could be one.
But with those conditions present along 2,000 miles of coastline on a regular basis you should have multiple attacks more frequently in various areas.
3 attacks in 5 days guys. The last two within an hour of each other. Roughly a mile apart
I'm going with a single shark that has figured out there are easier pickings other than baitfish in those waters.
