[PSUBS-MAILIST] new video

Alan,It is not my discovery, it is well known that the coral exists in Premier Lake.  Tim, we should plan a trip to Pavilion Lake with Gamma for the spring.  I will put a trim tank in Gamma so there is no risk of hitting the bottom.  I have been thinking about a plastic trim tank anyways to reduce the dry weight of the sub after the pod is on.  The down side of the pod is the extra towing weight.Hank

 OK Hank, you might have to think up a name for your new discovery.Any suggestions???Alan
