Luck on Cully's side
Other than his wife Bonnie cheating on him, let's consider how lucky this poor guy actually was. First of all, he's only a few yards away from "Faithful" the dog getting killed in the cemetery; then soon after, he's just as close as "Barlow?" does the same to Larry. He just dodged 2 major bullets, and he even gets to escape the 'Lot before all hell breaks loose.
Also, I don't think I ever saw this mentioned on the old board either, but he was also one of the volunteers in the woods looking for Ralphie Glick, and this was AFTER his wife gets caught with Larry. I think someone or some entity was looking out for Cully.
I'd love to read some thoughts on this.
