I'm going down to Port A. in May and bringing with enough equipment to safely keep alive and transport random critters, algea, etc...(all legally collected of course). So, what about collecting a cup of sand or so off Padre Island on the side facing the gulf to increase diversity in a DSB? I'm talking at least as far out as the second sand bar, that's what...at least 200ft from shore +/-. I don't have access to a boat or dive gear so anything furhter out is beyond me.
