That part of Highway 60 leads to the White Mountains of Eastern Arizona a couple hours north of Globe. There's actually another Apache rez up there. As far as pullouts, there are some old ranch or forest roads that lead off the highway. Many are gated but there's a wide spot in the road that people can pull off. There was no formal rest areas up that way the last time I drove it in 2016.
As far gang activity, not sure about that area of Mesa. My daughter used to live just south of that intersection until about 5 years ago. Her neighborhood was fine but areas around it weren't. I never liked that specific intersection.
Not much formal gang activity in Globe. There's a ton of drugs. In the 80s, it was coke. Since the early 90s, it's mostly been meth, but the movement is not organized enough to be called "gang".
