You just HAD to bring ice cream, didya chili?
Anyways, any ice cream is good, be it Edy's from the supermarket, a Friendly's sundae, a Carvel Brown Bonnet (it's a soft serve cone dipped in chocolate, but they also do make good ice cream cakes), or Ben and Jerry's (I've seen a store down in Virgina, Williamsburg area) anything. One thing I haven't had in ages is Baskin Robbins, but I still remember those fun flavors of the month.
A bit OT on ice cream, but around here, Italian ices are extremely popular. This one place we have, Ralph's, makes some killer cream ices, my favorite being rainbow cookie.
