Not much , and if you are after hali you need to go a long ways , and the winds can be ugly that time of the year , have a good GPS andf if there is someone there who is knowledgable of the area see if you can coattail him , DON'T and I repeat DON't go off on your own until you have been there for a few trips and get to know the area.
I haven't been out there yet this year and don't know how the sand bar at the mouth of the river has shifted so I can't give you any advice , except be very careful on tides lower than 2ft as last year at that depth you only had 3 ft of clearance without factoring in the swells.
