California Grasslands

With nearly 40 million people, California is the most populous state in America. But if you know where to explore, you can get lost in wide-open grasslands and green rolling hills. Greg uncovers one of the Golden State's best-kept secrets by venturing into Carrizo Plains National Monument and inter-coastal mountains during spring where green grass, stunning wild flowers and incredible views will make you forget you're 2 hours from Los Angeles.
