I won a trip to go to Willie Nelson 4th of July picnic. That is great, but it only includes airfare, hotel, and tickets to the event. so we are on our own to get to/from airport (plan to take supershuttle) and the picnic at the Stockyards. It looks like it is almost impossible to get there and back by bus (at least 2 hours each way, and no busses that late at night). I can't make heads or tails of the DART system. I understand traffic and parking and closed streets will make it no fun to rent a car. Is a taxi my only choice? Thanks for any insight!
