Houston Art Car Parade announces Cheech Marin as 2017 grand marshal I've been going to the Houston Art Car Parade for quite some time, my avatar is from when my brother-in-law entered one a couple years ago Lots of neat cars such as the Peep Jeep (yep, covered in marshmallow Peeps!) The Enterprise: and so on. I wrote up a long blog entry about our experience if you'd like to learn more about the parade. Also here's some photos from a prior year, Art Car Parade 2010 (1/2) and Art Car Parade 2010 (2/2). Those were from the year Dan Aykroyd was the Grand Marshal.
