yep it's a busy spot so always expect some company while the fish are running.
first light in the morning, and then incoming/high tide are your best bets down there. there is sometimes a small "last light" bite in the evening.
rigging = your mainline to a swivel, and on the other end of the swivel a 24" leader (most of the guys down there use MUCH longer than that), to a hook tied on with an egg loop knot to the leader material. you slide the corkie down the leader above the hook and put a piece of yarn into the loop created by the knot.
when you tie the leader to the swivel, do NOT cut off the extra inch or two of line from making the knot (the tag end). attach your lead, either pencil lead or split shot to that tag end.
that way when you snag up the lead slides off and instead of having to re rig the whole thing, you just need more lead.
a lot of the guys down there will have all kinds of different rigging methods all accomplishing the same thing. some will have their weight on a slider, some will be drifting essentially a plunking rig with super short dropper, ect. there are as many way to rig up as there are people fishing. Just watch what the guys that are catching fish are doing and try to mimic what they do.
