This is probably the best launch location in terms of safety of your vehicle and water access. https://matagordabeach.org/matagorda-ba ... sills-cut/
Never had any issues there or heard of any issues there and you don't have far to go to access the mid bay reefs. I know you're experienced just be careful when the east or southeast winds pick up even at 10-12 it gets rough on this end of the bay. 15 mph winds make it pretty much unfishable IMO.
You can also try 3 mile cut if you have 4x4 and are experienced in driving in sand. Not sure what the beach conditions are like now. 3 mile is not a place to go if you're alone for sure. Also your vehicle is more hidden. I've never had any issues back there but it's possible. https://www.google.com/search?newwindow ... hd:;si:;mv
