Locked Out

I was in a campground once where the guy locked himself out and his 3 year old kid in (the child was sleeping). He was panicked to get in before his wife returned. He ended up sending an older kid in through the fan vent in the ceiling - had to tear the fan out to do it, but it worked. I told him to get a locksmith (2 miles form town), but he was truly panicked. The child slept through the whole thing and I bet a new fan cost him a few hundred plus the install. A locksmith would've been cheaper. Come to find out, the trailer was brand new and borrowed from his dad. On his way out of the park, he put a big dent in it on a rock. He told me he was going back to tent camping.
