Art's route is not "classic", but it does have some fun climbing, and there will be NO line. There are a couple of tough sections that'll keep you on your toes. The moves off of the ground are strenuous and committing. Head up and right following the crack until it's time to swing back left over the overhang (2nd crux). Head up left to a belay tree.
Location
This route is a bit of a hidden gem. You'll need the guide book, and some luck finding it, if this is your first or only trip to the Gunks. But of course you shouldn't be seeking this route if that's the case. Anyway it is located on the Thom's Thumb pinnacle at the far end of the Trapps. Head up the trail near the "S" turn in the carriage road... When you reach the cliff go right Look for the crack system, in a left facing dihedral, on a free standing pinnacle.
Protection
Standard rack up to #3. You could rap from the tree, but the slings never stay in place since it's a quick easy scramble down the back and to the right and back around to your pack.
