I've found a snake in a guitar before. I'd say it's one of the first spots to look. I've had two escapes I've never found, corn hatchlings, but other than that I've had some lucky occurrences. One of my yearling corns decided to get into bed with my girlfriend and I. She woke me up in the middle of the night and picked a snake up off her stomach asking if it was mine, haha. Another time a sand boa hatchling got out but I found him right next to his container wrapped around heat cable. Derp. Other times I've found hatchling bps in my gf's duffle bags and my savannah monitor loves to hide in her shoes... Actually, I'd say that 90% of the time my reptiles are hiding in her things. They must like her scent.
