Looks great, Irv!
Fantastic looking pork chops.
Those aren't traditional pork "chops"... they're pork "steaks". I think this is a St. Louis (or midwest?) thing. Pork steaks are essentially a pork shoulder sliced anywhere from 1" to maybe 2" thick, then grilled.
Four hours?!
They are usually cooked over high heat until "done", then put in a pan of bbq sauce (and beer!) for anywhere from an hour and half up to, well... four hours. Braised, I suppose. They are amazing... unbelievable flavor!
