ditto on being discrete and not draw too much attention. i will occasionally have to travel through Vancouver DTES, along the hastings corridor in the evenings, and many of the zombies will start to roam. surprising there are also sometimes older asian folks walking amongst them, and they will walk about without any incident.
my main thoughts - try not to have any break down along that pathway - even if i get a flat - try to get out of that area before attending to it.
