the strip requires a key apparently and when I go to cottonwood cove with caesers mark I'm still attacked on site.

I figured out how to get back into the strip. I ended up having to shoot all the securitron guards, onces i killed all 5?.... i got a key off one and entered. no one else attacked me and my karma never went up or down. As for cottonwood, do you have Boone with you? He'll start shooting, they start shooting and it becomes a royal C.F.

Good luck!
