None. Lock your car and don’t leave valuables visible in it (I follow those rules EVERYWHERE). But it isn’t the kind of place where you’re going to get mugged or assaulted out of nowhere just because you took a wrong turn down a shady street. I’m a 38 year old female, I’d say my situational awareness is average, and Ive been running on all the “tree streets” and all over Manch regularly for the past 3 years and I’ve seen some sketchy stuff but never ever felt unsafe. Well, safe from the kind of thing you’re worried about - on plenty of the roads I’m extremely concerned about distracted drivers as a pedestrian.
