Artist Bill McCaffrey took 15 hours to complete a chalk painting of a Titanic scene on the street in Lake Worth, before the rain came and washed it away. But that's OK with him.
"The longer I do street art, I become less possessive of my work," he says. "You learn to let it go."
McCaffrey was one of the featured artists at the Lake Worth Street Painting Festival, in which he has participated for 17 years.
The two-day festival drew a crowd of nearly 100,000 people to the small town over the weekend.
