The crux is low near the ground. I found it impossible to avoid using the crack to the left of the route, which helped a lot. I'm not sure if this is off-route.
The Boston Rocks guide lists this as 5.5, so that's what I'm doing here, but honestly I think it's harder than that. Another sandbag.
I found this route in Boston Rocks, 2nd ed., p. 107. There are few details, just a sketch, so I'm guessing a little.
Find the large block which hosts "Twinkie," left of Snacktime Crag. At the right of this block, there's a thin crack which starts at the ground and widens as it goes up. "Yodel" is about a foot right of that crack. The route pretty much goes straight up.
Top rope. Bring long slings, good trees are 15-20 feet back from the edge.
