Rivet location

Hi,
Rivets are on man-made structures usually (I think). Are they usually on a roof or can they be on walls or beside the given building?

Rivets appear on roadside boulders too, plus other structures such as bridges.

So, if the location was given as a school the rivet might be on the roof, wall or in the playground? Guess I'll just have to go and look.
