If you’re planning to attend this weekends’ Sarasota Powerboat Grand Prix, there’s free trolley shuttle bus service from the Palm Avenue Garage to the Lido Beach Pavillion from 9a.m. to 6p.m. Saturday and Sunday. The Herald-Tribune reports city officials want to keep down the number of cars heading to Lido Key. Parking Manager Mark Lyons says they’re encouraging everyone to consider alternatives to driving. Lido Key parking regulations will be enforced for the weekend. Suncoast Charities for Children, the Downtown Improvement District and A.D. Morgan construction are covering the cost of the shuttle service.
