Fair warning
I’ve seen my fair share of “Danger of Death!” signs on my travels. Not that I’m wandering in particularly dangerous areas, but going hiking, or wandering around more rural areas and you’ll find power lines or electrical hubs, and it’s not a good idea to go too near them.
I like how adamant this sign is, though. It’s not holding any punches, with its big red “DANGER.” The added warning that yes, you will die, but also, it will hurt is the perfect little touch to try and get through to stubborn people.
