Well it's Spring Break right now so you'll have to battle the idiots and the influx of people and law enforcement on the beach. The majority of folks will between the pier at the jetties and the three mile cut. I always go at least a few miles past the cut to get to more desolate beach. Your best fishing will be near the jetties or at the north end up by the pass at Sargent. Surf fishing is good anywhere along the beach IMHO, so again I would pick an area north of the three mile cut and away from others. Your stock 4Runner will be plenty for the beach and will easily carry you up to Sargent and back many times should you choose to trek up there, I would suggest that you do it at least once. You can also head back into the marsh land trails on the back side of the island and fish the many back lakes and lagoons of the East Matagorda Bay, just caution where you are traveling and where you park in relation to the time of day and the tide. You can run the entire beach without airing down, I have done it many times, but I would suggest airing down a bit if you have the time, it'll make for a better ride in the fluffy stuff. I will be out of town this weekend, otherwise I would offer to meet up. Enjoy yourself and watch the tide.
