Yes, my main concern is the cartels themselves. The most likely outcome is that none of them would ever agree to meet me. There is a very small chance that one or two would meet me, love the idea, and agree to cooperate. There's also a non-zero chance that in the process of trying to get a meeting, I would upset them somehow and they would take some action against me. Another possibility is that even if the cartels like my idea, it might upset other parties in the supply chain and they could take action. Billboard is a good idea. I'll look into that. What should it say?
