How many summers do you think you're going to have? How old are you? You plan on having another year of "Oh, that was the summer that I...didn't do anything"?
Come on! Fireworks. Hot Air Balloon. Go get a sunburn! New Roller-coaster. Go re-enact something. Visit a weird food festival.
I'll get you started
There's a group visiting here with WWII fighter jets. I'm very tempted to take a ride. Wouldn't that be a weird thing to put on my death certificate? Died in crash of a WWII fighter jet.
Nice weather. Go have sex outside
