Very shallow reefs where I usually surf but I sit in about 6 feet of water and paddle about 10 feet in towards shore over about a 2 feet and less deep reef so Im safe for most of it. But yeah your right.

I dont piss in the water if i can help it theres amonia in blood and in piss too and a great white can smella drop of bloodat about a mile away so I figure
1 +1 =2 in this case. So Im keep number ones to myself .
