I also tend to get out and walk. Not so much out of a desire for fitness as from crushing boredom. I've never felt 1/4 as threatened *anywhere* in Europe as I did when I made the mistake of walking a few blocks north of the hovel right here in River City. With the possible exception of the time I walked through "bum tunnel" in CGN alone at like 2am, but I'd been specifically warned not to do that, and did it anyway. And of course I don't go super-far from the hotel in like Delhi or Bangkok.
But *Britain*? I walked for eight HOURS all over Nottingham (and not just the tourist areas), which is famously not exactly the nicest post-code in Blighty, and I felt as safe as joey in mom's pouch. OK, wrong continent of weird-talking English-speakers for the analogy, but you get the idea.
There is something extremely weird about the modern Murican tendency to see an imminent deadly threat behind every telephone pole, as we've discussed in other threads.
