They say L.A. isn’t a walking city, but I dare you to try it. In Episode 8 of 'Allergic Reaction,' I set out on foot in the same black denim overalls to explore L.A.’s newest ruins and decaying landmarks. Along the way, I meet some really interesting people and have some unexpected conversations. First stop: Oceanwide Plaza, the billion-dollar ghost tower turned graffiti mecca in Downtown L.A. I meet Kyle (@CHELLYZTV) who is a multi-hyphenate photographer, actor, brand builder. We talk real estate, street art and what it means to spend a billion dollars and still fail. Nine months later, I hike up to the abandoned Old Zoo in Griffith Park, where I meet Arshak (@ACLandmarks), who broadcasts his own insights into the 'Assassin's Creed' franchise. He and Phee Chai @pheechaixiong were shooting a video, and casually invoking Julius Caesar as a modern-day model for taking civic action. Then, I tag along with Dave and Grandy. Dave’s an author who is also building a Museum of American Humor. Grandy is a wearable artist who turns Amazon boxes into couture handbags (@atelier_grandi, featured in VOGUE). She calls her work a real-life "allergic reaction.” We couldn't agree more. None of these encounters were planned. I only learned who they were after I Googled them post-shoot. But maybe that’s the point: You never know who you'll meet, or what forgotten places you'll find, until you actually get out into the world and say hello to strangers. Each interaction changes the course of the future trajectory, somehow. (A lesson I learned from the film 'Back to the Future.')
