7,000-Acre Wildfire Sparked By Gender Reveal Party

A wildfire that has spread to more than 7,000 acres in San Bernardino County, CA was sparked during a gender reveal party, fire officials say.
Partygoers used a “smoke generating pyrotechnic device” that ignited the fire Saturday morning at El Dorado Ranch Park.
The fire has spread to over 7,000 acres and forced 3,000 evacuations so far.  It’s one of 23 major fires burning in California right now.
Has the ‘gender reveal’ fad gone too far?  What’s the dumbest thing you’ve seen someone do at a party?
