We won't buy anything from Ben and Jerry's. However, SWMBO and I are both ice cream freaks. We had a serious run on Bruster's a couple of years ago (their plain chocolate, mint chip, or vanilla/heath). When I'm back in MN, I always try to score a little Kemp's Maple Walnut when I can find it.
For some reason, I seem to gravitate towards plain vanilla at home, and other stuff when I'm out.
