The Walker family has worked in the transportation business since 1963, when it opened a six-car rental operation in San Antonio. In 2006, the family sold the rental company—which had since grown into an international enterprise—to focus exclusively on its Texas-based limousine and shuttle services. Abbey Walker Executive Cars & Limousines's current fleet includes classic and stretch Lincoln Town Cars in black, white, and phosphorescent glitter-green. Groups can also cover ground in vans or buses equipped with luggage racks and wheelchair lifts. Uniformed drivers chauffeur groups on pre-planned tours of Texas wine country, complete with restaurant reservations and hypoallergenic wine-stomping stilts.
