About 150,000 people flocked to the area over the weekend to see this year's bloom of orange poppies brighten up the hillsides. The crowds at Walker Canyon, which is about a 90-minute drive from San Diego or Los Angeles, became so large that on Sunday local officials closed the local access road. The shutdown, which was a hot topic of discussion on Twitter under the hashtag #poppyshutdown, ended on Monday and the road to the canyon re-opened. [Photo: AP/Gregory Bull]"
