Laurie and Jeff Smith's family is of the many military families currently living at the Keesler Air Force Base in Biloxi, Miss. Their base housing is fine, except that it's so cramped that only two of their four children are able to live with them. The rest are staying nearby with their grandmother. After 13 years of moving from place to place, they want to buy their own home, with enough space to bring their family back together under one roof.
