Dogtown does look like the best. Salt Lake City woudn't be that bad though, a dlc of a city covered in mantis sounds pretty fun :ninja:
I mean it's really covered with 'em.
You wouldn't even be able to move.
The ground would be mantis' on top of other mantis' on top of
other mantis'.
Would be challenging though, stimpacks are bound to run out at some point.

Salt Lake City would be pretty cool, giant mass of mantis' that would be a near first in Fallout or it may have more mantis' leaving mantis deposits idk... Giant mantis mines to explore maybe a new breed of mutant mantis miners do to all the mantis around them and there is lots of mantis sites they could mess with.. lol idk who knows but what ever they decide its still ---> http://www.all-creatures.org/pica/glf-mantis-27b.jpg
