After seeing Dave's place I am convinced this was no random drive by act. This was a walk in by people who had a grudge and knew what was there. They may have even watched Dave drive off. They were bold, as that had to have made a lot of noise and echoed all through that canyon. But it was a surprise attack. That element is long gone and the target will be in plain sight taunting them.
I agree completely. I said the same thing to Dave. Someone was watching and knew he was gone. Pushing the boat over the spill way and down into the ravine would make one heck of a racket, let alone hitting the boat with concrete chunks.
