I grew up in Sunnyvale in the 80s and this made me nostalgic for the old days of Silicon Valley. I had always heard that sometimes the gas from the dump would ignite from smokers at concerts. I guess it's true! "In its opening year, a fan attending a Steve Winwood concert flicked a cigarette lighter and ignited methane that had been leaking from a landfill beneath the theatre. Several small fires were reported that season. After those incidents, the city of Mountain View commissioned methane testing studies to define the location of methane vapors emanating from the soil within the amphitheater. These tests were used in developing a design for improved methane monitoring and more efficient methane extraction to ensure the amphitheater became safe as an outdoor venue. Ultimately, the lawn was removed, a gas barrier and methane removal equipment were installed, and then the lawn was re-installed." https://en.m.wikipedia.org/wiki/Shoreline_Amphitheatre https://en.m.wikipedia.org/wiki/Shoreline_Amphitheatre
