The first set are directly next to 13 by the Park Blvd exit. You can see them from the road. I never tried em as I didn't have a bike for em. I'm pretty sure the set in the video are from directly up the hill from there. Look on Google maps in satellite view and you can see where the power lines run up from the first spot.
The first set isn't the one of 13, those are gone, it's a set of jumps on top of a hill with radio towers. If you're from around here and you know where the parking lot is with the two baseball field then you know where the first sets at.
The second set is in montclair, coincidentally also next to a radio tower.
