Yes. Hundreds of times.. but not since Harvey. Before Harvey the main entrance was very rutted up and trucks with trailers were getting stuck daily. There was a harder gravel road to the south about a 1/8th mile that would allow you to essentially go around the rutted area and stay on hard pack gravel and sand.
Dont' leave anything in your vehicle. It's been a bad spot for theft over the years.
Fishing can be good June - Nov on both sides of the cut for reds... and on the Shamrock Isl edges for trout. Nothing big on the trout side this time of year but there's enough fish to fill your stringer.
