Congratulations to all.
While I mastered the fall off the bones babyback ribs, now I need to master the exposure. Should have masked that area ab brought it forward.
Incidentally, on the ribs, when slow cooked on grill they would be tender but dry out. Tried slow cooking in a crock pot for several hours. They were ultra tender fall off the bones but soaking wet. Finished by putting on the grill for 20 or so minutes as the veggies cooked (coated in olive oil, salt and pepper) and spread BBQ sauce on ribs plus carefully flipping allowing to brown on both sides - thus the dark color. The excess water evaporated on the grill but still moist and tender.
