ACL as the rain started...
Once everyone covered up
The day after all the rain was a mess
Put anything you want to keep dry in plastic bags in your backpack. I kept my cell phone in it and only took out to text or take pictures. The sandals I packed had buckles on the back to attach to my backpack for when the rain turned into mud but it is better to use rain boots than go barefoot...esp in the bayou of Houston.
How to survive a rainy music festival:
Poncho and umbrella if they allow umbrellas
Rain boots or sandals that you don't mind getting nasty
Sunscreen
Sunglasses
Refillable water bottle
Plastic bags to keep your cell and electronics dry
Backpack
Baby wipes
Extra towels to clean off before getting into car
