fishincrazy are you talking about the smooth cement bowling pins at Manasquan when you say jacks? I didn't think anyone could walk out there without korkers, that must have been insane.

My story isn't that exciting. One time a friend and I who didn't know better went out on a concrete filled jetty, so it wasn't that bad. One part was slippery, and he fell and gashed his arm. We learned that even the concrete ones have wet slippery spots.
