Excellent problem. If Tucson has a list of classic boulder problems, then this is right up there with the best of them.
Begin at the left of the undercut and traverse right on small edges to a crux gaston move and throw for the lip. Depending on one's height, this is a feet-off very dynamic move. Throw a heel and top out. Enjoy.
Location
As you approach the A-frame when walking around the upper cave boulder, you will walk right by The Rails on your left before entering the A-frame. There is an undercut to the boulder. The chalk is evident and The Rails is the only problem there.
Protection
Pads are nice, but the landing is OK and not off the deck at all.
One of the best boulder problems I've been on in a while.

fun. would be way harder and way cooler without the glued jug in the roof. also looks like there is a line starting just down and right from the gaston hold that finishes the same but is quite a bit more difficult.
