I used to work for U.S. Forest Service Descanso Station in 1987. Balloon landed at the station. It got a note saying came from school in Point Loma.. They do travel and trash the wilderness
Thank you for posting and doing a story about this litter! Here is the petition to ban the sale of helium filled balloons that litter the desert, ocean, harm wildlife, cause power outages/fires, and use up the finite resource helium. www.change.org/banmylarballoons
