NetDoc: Poor choice of words, not meant to promote divisiveness. The responses on this thread have been reasonable, polite, and interesting--and from quite a few of the SB "veterans" with much experience. Some of my past experiences on old threads and on boats were in fact much more divisive.
drbill: Excellent example of some of my past experiences, except the person involved may do the opposite-- chastise me for collecting shells while committing something perhaps considerably more ecologically offensive.
If I may be a bit dramatic: People who don't collect live (or even dead) shells because they simply think it's wrong, I have no problem with at all. Those who preach not to because PADI (or whoever) says if you ever even touch anything alive the world will shrivel up and die --and well, without any real knowledge of mollusc populations--well they're just taking that as gospel and thinking they are in the know, have been educated, and are 100% doing the only right thing--figuring why would ANYONE do otherwise, "do they not know what I know?".
On a boat in Panama, guy (PADI Rescue Diver) says to me "PADI says you shouldn't even touch anything live". I said "Yeah, and PADI says you should have a snorkel on your mask".
