When Jamie is not crunching numbers she spends her time watching college sports with her family and going to the beach, activities shared by most card-carrying North Carolinians. However, since Jamie went to UNC and her husband graduated from N.C. State, game days can test the mettle of their marital civility - especially with their young son in the mix.
