It was also a bit cloudy so I could just hold the camera (I don't own a tripod) and well I was lucky.
Doesn't look like you need a tripod.

JFreak -- thank you for the explanation. That explains the names and initials on the locks.
mikshayne -- you don't have to go back. You said you found your initials there already.
