When i was younger used to ride down to the local long distance truck park and take pictures of various trucks still got the slides of them.

Met some intresting people and some a bit dodgy but you do in all areas of life.
Goes off to drole over Volvo f86 and f88 tractor units, and a lot of scammell constructors and crusaders along with the leyland t45.
