those are good questions! idk about when they get out, but for the second probably somewhere where experimenting with humans is less illegal, so america could be an option (and probably easier since we have a good diverse mix that is generally only found in the usa) since genetically modifying organisms is a-okay. probably can't be europe, since theyre SUPER strict with this stuff. thisll be illegal everywhere anyway, though. the question is: what part of the US?
they could also be in Antarctica. if you want to make it nearly impossible to escape.
