Well, obviously the Shreveport casinos are out! If your girls like shopping, there's plenty to browse on the Louisiana Boardwalk and the along five-mile long Line Avenue (hmm, though maybe not the best recommendation for sticking to a budget?!). You could take in an indie film at the Robinson Film Center. Or catch a rock or country-music act at the historic Shreveport Municipal Auditorium. lastly, stroll the city's acres of pretty gardens and parklands, including the trails at lakeside C. Bickham Dickson Park. Hope this helps!
