Salad Olivier -- Russian Potato Salad

I found this Russian Potato Salad called Salad Olivier on Smitten Kitchen. It is a very simple potato salad but the addition of dill pickles, carrots and peas makes it a little different. I never bought dill pickles before and I didn't realize there were 20 different kinds of pickles in the store. It took me good 10 minutes to figure out what to buy. Carrots and peas make the salad look more colorful.
