Hmmmm.. LOL.
I remember each of the erosion events you spoke of as each was a big swell for avid surfers like I was then.. I still remember finding my first 1715 cobb after the Thanksgiving day swell.."88" I think and the monster Halloween swell of "91" was also very good.
I actually eyeballed it before I swung my detector over it.
