At one of my hills it's probably a rainbow rail they've had for 5+ years, with no lip on, 6+ feet tall, it hasn't been re-fabricated, waxed, re-welded, or hit in some time.
At another mountain which I've been frequenting this year, it's either a 22' Double Barrel Elbow rail, or a 25' Flat bar with a flat-bar closeout lip on, but if you spin left onto the rail, you'll hit the closeout because of the tiny ass lip, so unless you can lipslide like a champ, people who slide right foot forward can't really hit it.
My other ride is your mom.
