I’m thinking that a starting site where you are one of many workers at a construction site would be fun to play. As a plumber myself, I can tell you that you would also be likely to find shit loads of rocks, random tools like saws, shovels, welders, hammers,toolboxes, and work vehicles, etc. along with pipes, scrap metal, nails, lumber, fencing, wire, sand, pebbles/gravel, etc. there could even be an abandoned foodtruck to loot.
it could be a rare spawn regularly, but I’m thinking that electricians, handymen, Security guards, commercial cyborg, etc would be the professions for this.
