Like Dorothy in the “Wizard of Oz,” the Southern California city of Lake Elsinore is being overwhelmed by the power of the poppies. About 150,000 people over the weekend flocked to see this year’s rain-fed flaming orange patches of poppies lighting up the hillsides near the city of about 60,000 residents, about a 90-minute drive from either San Diego or Los Angeles. Interstate 15 was a parking lot. People fainted in the heat; a dog romping through the fields was bitten by a rattlesnake. A vibrant field of poppies lures Dorothy into a trap in the “Wizard of Oz” when the wicked witch, acknowledging that no one can resist their beauty, poisons the wildflowers and she slips into a fatal slumber until the good witch reverses the spell. Lake Elsinore had tried to prepare for the crush of people drawn by the super bloom, a rare occurrence that usually happens about once a decade because it requires a wet winter and warm temperatures that stay above freezing. It offered a free shuttle service to the top viewing spots, but it wasn’t enough. Sunday traffic got so bad that Lake Elsinore officials requested law enforcement assistance from neighboring jurisdictions. At one point, the city pulled down the curtain and closed access to poppy-blanketed Walker Canyon. “It was insane, absolutely insane,” said Mayor Steve Manos, who described it as a “poppy apocalypse.” By Monday the #poppyshutdown announced by the city on Twitter was over and the road to the canyon was re-opened. And people were streaming in again. Young and old visitors to the Lake Elsinore area seemed equally enchanted as they snapped selfies against the natural carpet of iridescent orange. Some contacted friends and family on video calls so they could share the beauty in real time. Artists propped canvasses on the side of the trail to paint the super bloom, while drones buzzed overhead. Patty Bishop, 48, of nearby Lake Forest, was on her second visit. The native Californian had never seen such an explosion of color from the state flower. She battled traffic Sunday but that didn’t deter her from going back Monday for another look. She got there at sunrise and stayed for hours. “There’s been so many in just one area,” she said. “I think that’s probably the main reason why I’m out here personally is because it’s so beautiful.”
