Coachella is always preaching sustainability. Don't buy a lot of water bottles. So many people drink half of them and either forget which bottle is theirs or don't even throw them away and they get everywhere! Bring a 5 or 6 gallon jug dispenser full of potable water. Everyone at camp can use this water for drinking, rinsing hair, etc. I brought this last year and it was honestly the most important thing I brought.
