The Art Car Parade, in its 25th year, officially started with just 20 cars and a handful of spectators.
Now, it's one of the city's largest events and draws visitors from across the country.
It's put on by the Orange Show Center for Visionary Art. Wendy Schroell is the development director and says they have 277 entries this year.
"We have cars coming in, well they're here now, coming in from all over the country, from 23 different states, Canada, Mexico. People just come all over to see the Houston Art Car parade which was the first one of its kind and considered kind of a mecca for the art car artists. They all say you have to do Houston at least once."
If you've lived in Houston for a while, there's a good chance you've seen art cars driving around all year long.
Schroell says all different kinds of groups get together to create art cars each year.
"We have such a great community of artists here and it's just once you go to this parade you either know you want to do an art car or there's nobody that comes one times and doesn't come back to the Art Car parade. This year Rice University actually has an art car class, and they're putting in — it's their centennial — so they have the CentenniOwl Car, there's a wonderful Rice Owl art car in the parade this year."
The Art Car parade gets underway tomorrow at 1pm and runs down Allen Parkway. For all the parade details and schedule, visit the Art Car Parade.
