@rickubis Most memorable visit is a bit of a story: my son's kindergarten field trip. He's partially-sighted and has only black, white and grey color perception. He held my hand as he heard about alligators he couldn't see. Then he saw something and swooped to grab it! A coral snake. I pulled him back in time. Next day, teacher/nun said they thought I was "overprotective" and didn't want me on future field trips. #coralsnakes #Texas
