Picnic Select foods that are easily transportable and waterproof. The thick skin of bratwurst will shed rain; pre-warm the brats so you needn’t tend charcoal briquettes in the thunderstorm. Skip the buns (too soggy) and simply eat them with your fingers as you sit in the car watching the windshield wipers go back and forth.
Parade Keep those wipers going! Otherwise you’ll miss the marching brands with their drenched uniforms and rusting instruments. Crack the car windows open to prevent windows from fogging up.
Road trip Plan a day trip so you can see what a scenic spot or historic monument looks like in a driving downpour. Bring a change of clothes (or two or three) to use after the inevitable dash to a public restroom.
Sporting event Whether you’re participant or spectator, Memorial Rain weekend’s running and biking races have extra zip as lightning fills the air with ozone.
