I actually don't have a favorite beach.  I hit spots from Foulweather Bluff to Restoration Point and pick the specific beach based on wind, the tides, and how much time I can spare.  I'll focus on beach fishing in MA9 until there are signs of ocean coho in MA10.  Even though we can't fish from from floating devices in MA9, I will mostly kayak to secluded beach to avoid crowds, especially on the weekends.
