" The 61st Annual McDade Watermelon Festival in McDade Texas (about 50 miles east of Austin) is a model of Car Show organization. Not only is there no entry fee (although they encourage a $5 donation!), but the grounds are marked, the folks that greet you are friendly and informed, and everyone involved seems to be really pleased to be a part of it. As far as I know, it is not a car club, though the Bastrop Cruisers do get the shaded parking.
Never any good at estimating how many cars show up at various events, I would still guess that there were around 150 rides of all type....antiques, muscle cars, customs, hot rods and even some very old and rare farm tractors.
