Am I Cheating? Options

[Old Geaser]

This is something I have wondered about ever since my 1st generated act.

When I make a activity, there is always some cars listed to be picked up, but there is no set out location for them. What I have always done and was able to get a completion, is just set them out on any siding that is not listed to have a set out. I set out each unassigned set out on the nearest siding, not all unassigned set outs on one siding. I assume this is what I am supposed to do. Correct? Thanks
