anyone know how to cook ribs so they are nice and tender and not dry?

sounds fabulous!  when are you making them for us?!  ;-)

What kind of ribs?  If you're making pork ribs, throw them on the grill (plain, no sauce or seasoning) and brown them on both sides, first.  Then, put them in a roasting pan, cover them with your sauce, cover with foil, and bake them in the oven at 250 degrees for 3-4 hours.  They're so tender and moist, the meat literally falls apart.
