I would assume if they are a yard crew working an area,they case yards by day and come back at night, I am no Sherlock Holmes, but that would make the most sense,one of the people told me he saw a landscape truck and trailer (red trailer) with no markings driving up and down his street the day before he had a carrie mango he just purchased stolen, just sucks cause now he dosent even want to replace the tree fearing it would happen again,cant say I blame him, but you cant let fear rule you either. I would say these fools are no brain surgeons,sooner or later they will hit the wrong place.,problem is who is gonna prosecute these guys when they cant even put real crimminals in jail.
