Re: Police station mapping
"Back in the very old days when every town had a police station that actually opened its doors more than one hour a week, they were usually well signposted and always had a town map on the wall in the lobby. Other good alternatives were petrol stations and estate agents."
Catch-22. You need a map to find the place that has the map.
"Even now there's always the option of winding down the window and asking for directions. Human interaction has its advantages sometimes."
That was before carjacking and similar crimes became en vogue. And there are definitely places that are not safe for foreigners to tread, no matter the local foot traffic patterns.
