What's your most interesting service location?
I've got machines in prisons, which are often not the kind of interesting you want.
One on an island that was delivered by ferry then carried on horse drawn cart to its install location. I have to walk to it every time for service, up a rather steep hill.
A couple in an administration building between a set of locks so I can often look out a window at a large freighter going by during service calls.
Every year we rent a copier to the local fair grounds for a week.
