Coming down Manning run on Seymour, you can go left into Velvet Gully at one point. Trouble is, you have to cross the fall line used by people doing side hits up to that point. I ride regular, so of course that's my blind side, so I've gotten in the habit of using a hand signal when I'm about to turn into the Gully. Served me well a couple of times.
No, not THAT hand signal. I use the INDEX finger.
