There is a park covering an underground parking garage in front of the George R. Brown Convention Center (home of market and festival). There was a series of art globes with an ecological theme in the park. They reminded me of the art cows from a few years ago. I walked in the mornings and saw most of the globes – but I didn't have my camera! I did manage to take these on one of the trips back and forth between the hotel and market.
I didn't get out much so took these photos on the run.
