Probably the neighbors with the great big POD in their driveway.
I’ve ratted out my Mexican neighbors before. Of course they were remodeling their garage to be able to rent out rooms (typically $500/month) for illegal aliens migrant workers. They stack them in like cord wood in their converted rooms/garages. The give away were all the new satellite dishes so they could watch telemundo and soccer.
I did another neighbor because he was adding on to his garage and laid his roof trusses on their side instead of on edge. They were Mexican too...
