I was headed back to the ramp behind a wake boat yesterday. He was traveling about 25 mph. I was back where his wake settled out. I noticed a flap on the back of the boat open. It started a nice high rolling wave off the side of the boat. At this point I see a bass boat pounding the bank. Fella had his fishing shirt and gear on. Tournament stickers on the boat. He was obvious to the wave headed his way until it was tossing him around and washing over the sides of the boat. Man in the wake boat closed the flap and never let up. The bass fisherman had some might fine balance to stay upright on the front deck
