Against what? Zombies? No, RATS! Interesting story about the NY subway rat situation.
NYC has been studying how to fight the rat population, with the conclusion that it is not likely to be a winnable war. At least some folks are costing out this one war before really kicking it off:
Indeed, a spokesman for the transportation authority said Tuesday that the agency would “need to evaluate the costs associated with implementation moving forward.”The good news is that the population is not as big as feared, and the rats are not likely to ride any trains since "the stress of noise, vibration, and crowding may kill some of them before their time.”And that would be a pity. Or not.
