As an adult, Mr. Tullock got in touch with me, sending me his drawings and submitting to my interview questions. I was satisfied with his responses. Here are excerpts from the blog Live Pterodactyl (Texas pterosaur sighting):
This thing flew over my head, about eight feet off the ground, and stopped and hovered in mid air. I was facing west, so the creature flew from east going west which means it came from our land across the road, which is a nice mix of oak and pine forest and thick swamp. . . . It stopped in mid air and hovered there by flapping its featherless, bat-like wings, which were about four feet in span, maybe five. It had a tail about three feet long, with the . . . flange on the end . . . no head crest and no feathers at all, although there was kind of a longish bump on the back of the head. . . .
