FORT WORTH -- Sunny skies, temperatures in the high 60s and half-price admission lured more than 20,000 people to the Fort Worth Zoo on Wednesday."Things were hopping today," said Alexis Wilson, the zoo's spokeswoman. "It was a perfect day for us."An official head count wasn't available Wednesday.Wilson said that as some point during thd day, ticket-takers stopped scanning tickets and started taking them by hand to move people in faster. So the tickets will have to be hand counted, and zoo officials won't know the final attendance number until Thursday.The record for a spring break Wednesday was 2010 when 25,804 tickets were sold.Fort Worth police reported no major traffic problems, although motorists stuck in traffice might disagree.To avoid traffic through Saturday, zoo patrons are urged to take the T's "Safari Shuttle" from the Intermodal Transportation Center downtown. The shuttle runs every 30 minutes, 9:30 a.m. to 6 p.m. A round-trip day pass is $3.50 for adults, $1.75 for seniors 65 and older or with transit agency reduced ID card. Children under age 5 ride free.
