VHS ALERT: BOATERS & ANGLERS

Da wording on a dockside sign dat warns aquatic sportsmen about of a serious bacterial infection of fish caused by throwing videocassettes into the water.

I always find da "VHS ALERT: BOATERS & ANGLERS" signs puzzling, since conceivably most folks who would be venturing out on a lake or river would not even have televisions or VCRs with them, and so there should be little problem of folks tossing their broken/unwanted tapes overboard while they were cruising around in their skiffs and yachts.
