Swimming to a dynamite show

I'm on vacation at the beach with my parents. We're staying right by the shore and have tickets for several baseball games each day. I decide I want to go swimming instead of seeing a game. The beach is so steep, I have to climb down it hand over hand. I have trouble finding a place for my towel where it will stay dry - the waves are large and violent - it ends up getting sopping wet.

I take to the water and decide to swim out to a long island parallel to shore. On the way out I pass a Latino man and his son and greet them.

I'm on the island and join a group of people sitting in bleachers on a driveway. A guy dressed like a magician in red satin comes out of the garage and starts his show, talking about how wild and crazy it will be. I walk down closer to him. He lights a stick of dynamite and throws it in the ocean. It hugely explodes, sending water all over the crowd. In a few seconds, a spout of muddy water comes up from a secondary explosion, we're pelted with clumps of mud.

After an intermission, the performer comes back saying he hopes he doesn't get arrested for doing his second act. Laughingly he reassures the audience everything is very safe. "If it wasn't, I wouldn't be able to do this!" He throws two lit sticks of dynamite into the bed of a pickup truck driving by carrying what look like three huge dry wreathes of vines. The truck explodes in a huge fireball. The magician tries to escape in the same direction the truck was going, but is soon brought back, arrested by police. They search his garage and find a cupboard packed with dynamite.
