Many of the best known LACs are located in rural areas (e.g., Williams, Kenyon, Carleton, Sewanee, etc.). In addition to the urban LAC suggestions offered by earlier posters, I would refer you to Occidental College in LA.
I would also second Rice, which is an academically impressive and very fun small university (4,000 students) with the vibe of a LAC, and which boasts a beautiful, tree-filled campus located in an nice area of Houston–the nation’s fourth-largest city.
