I was throwing out some structure this past weekend on the Big Sandy and noticed a rather large boat driving back and forth all morning long. Well come to find out it was a garmin/gps survey boat. I have come to the conclusion that there where getting new underwater topographic information(contour lines) for the area. Has anyone else seen this boat in the area. So keep an eye and ear open for any new info that may possibly be coming out. b/c it will be up to date. only one proplem though they went over my structure after i threw it out so now everyone will have coordinates on it in no time
