if you don't want to head all the way to dog beach for ghost shrimp, you could head to mission bay directly across from the roller coaster and pump shrimp, there is a pretty good assortment of both large middle finger sized baits to the small stuff. The cool part about this spot is that you can fish there and catch corbina in the bay(you'll also pick up Turd rollers, shovel nose sharks and a bunch of other stuff.
Question....for ForkTail.

I noticed that you fish IB alot, do you know if the channel at the southernmost end of IB, is giving up the leopard sharks...usually this time of year they congregate in the channel.
