Traditional Potato Salad

We enjoyed the new potato salad recipe last night with some BBQ chicken, corn on the cob, and watermelon.  It was the perfect addition to a summer meal! I did not add the relish or red onion but used the other suggested ingredients.  After reading the suggestion about using sour cream or yogurt in place of the mayo I decided to do a combination of both sour cream and mayo which I thought was quite delicious!
