Rider: Zach Sciacca. Location: Mt Baldy, CA. This is a photo from one of my best powder days from last season. My friend Zach (also known as DJ Z-Trip) invited me to come up when we heard it was going to dump. I'm amused by this photo because of the sign, notifying that this trail was for experts only, and one of the world's biggest DJs is trying to figure out how he is going to make it down.
