Baked Beans - Marcia's Recipe

My sister-n-law makes the best baked beans -- I mean the best!  She shared her recipe with me today, she said it was given to her by an old friend.

I'm ready for a  BBQ so I can make these beans.  Now I'm on the hunt for the perfect potato salad recipe.  Got one to share?
