ETA: No trees? WTF? Sacramento has more trees per capita than any city in the world (okay thst might be a little exaggeration, but still...). And what is that I see for hundreds of miles along the northern highways? Oh yeah, giant fucking redwoods!
Yeah, it is kind of an unfortunate choice to pick the state with the world's largest and also the world's (currently) oldest tree and call it treeless. It's like going to the Himalayas and saying "It's too damn flat here!" Trees are kinda our thing.
I think he needs to visit Griffith Park or Angeles National Forest or something, both right there in or directly next to LA.
