Yes, those are the pits. The one off to the right is where I have been going for the last few weeks. There is also another pit off to the left that I'd like to hit some day after I get my boat legal and water ready. It's quite large and down the hill. There are a couple places to launch a boat and yes you are correct about needing a 4 x 4. I have been hung up on back into the path ways. There are several dips in the path and 4 x 4 tracks, just be very careful going back there. There are several pits back in there of various sizes. When I went this past Saturday I hooked into 13 bucket mouths. One of my best days yet. Now granted, only about half would been keepers but it's the thrill of the fight I'm after. I thank the fish then God for puttin that fish on my hook, otherwise I'm not that good. HA HA HA
If ya go back in there, best of luck and happy fishing.
