Easy trad climb on good rock with decent pro. Great way to introduce people to trad climbing, or to get back into it after an absence. If you've led 5.4 bolted slab, then this should be a step up :)
Follow directions on main Herring Creek Dome page. The climb is on a prominent right-facing corner, just to the left of the toprope area.
The first part of the route follows the right-facing corner up. Nuts, cams, and even a tricam placement or two should be available. Pretty good stances are available. There is a bit of sand, and a bit of munge here and there, but all in all pretty nice.
The last 20' or so is on unprotected but easy slab. Trend up and slightly right and belay from gear.
It's a casual 4th to 3rd class walkoff from there, and/or you can lower your second 150' back to the start of the route. We did it with a 60m rope however.
Nuts, cams to #3.5 or 4, tricams if you want. Nice route for practicing pro placement / cleaning, so bring what you want :)
