The crux is above the pentagonal-shaped rock where you start. Getting up on top of that is awkward, because the rock above it bulges out a little, pushing you off balance. I got over this bulgy area by mantling. It was not easy! I'm short (5 foot) - taller people may find it easier.
Once you're over the bulge, you'll be standing on a nice, wide ledge facing a sheared rock face with small crimps on it. I've been told there are decent holds higher up there, but I just pulled myself up high enough to tap the anchor carabiners and then lowered.
I found this route in Boston Rocks, 2nd ed, p 107. The only detail is given in a rough sketch, which is what I used to locate the route.
At the base of Snacktime Crag is a large pentagonal overlap of rock, about 5 ft high. Start climbing up the left side of this chunk of rock, and go straight up to top out.
Top rope. Good trees are available about 10 feet back.
