There's Trailside that goes from field to field. I was told it was knobbed again, but who knows. It gets knobbed/de-knobbed so much.
And there's Ecker Hill rail (down with a short flat). Sick rail but again, I was told by some kids that go to school there that it was knobbed again. the ones in the parking lots on main street are pretty short. there is a green quad kink behind some apartments behind taco maker/jakes. it's ok.
