Myself on Arete of Regret, about to give it a dese...
This is a nice looking route from the ground. It would be great if the rock didn't turn to crap 3/4 of the way up. Thus, this route is best TR'ed from the same ol' anchor 'pocket' as the other routes on Choss Boss Crag.
The rock surface texture becomes sandy and will not hold pro higher up. A fall here would not be fun. It is still a nice little route with a good alpine feel to it for the area.

Hike up to the Ace Dick wall, then head south a bit. Stay under the crags. After a couple hundred feet, you should be able to view the Choss Boss Crag (which this route is on) ahead and on the right. Virgin Mary on a Schwinn and Arete of Regret start at the bottom of the crag under the large tree.
To descend back to the lake, walk south under the tree, and then descend the long scree gully. This is faster and more fun than the scree gully used to access the other routes.
Typical trad rack. Small nuts came in handy. Long draws help cut down on ropedrag. There is a small horn 3/4 of the way up that I have slung and rapped/retreated off of before. Not a good piece when you're above it but it's good info to have...
Again, the same anchor bits for the neighboring Tourist Route, I'm Lichen This, and Virgin Mary on a Schwinn apply. I bring some nuts (or small cams) and a long cord or webbing for the anchor in a solid stance at the left edge of the rock at the top (You can't miss it).
