Homemade BBQ sauce and Ribs!

1 BIG containers of Ketchup (I think its 4 cups) so for every 4 cups of ketchup you put in:
1/2 bottle of green tobasco sauce
1/4 c vinegar
1/4 c worchestershire
1/4 brown sugar

Boil Ribs for 3 hours (turn it to high and bring it to a hard boil than turn it on low for 3 hrs.) Grill Ribs just to brown them, soak in the sauce in a sauce pan.
