<p>Many years ago, our next door neighbor’s kid was the concertmistress of the Central High School orchestra here. There was a big to-do, because the orchestra had plans to go to a youth orchestra competition in Vienna, and the State Department had just put out a notice warning people that airport security in Vienna was not up to international standards, and that there was a risk of terrorism in Vienna. A number of the parents wanted to pull their kids out of the orchestra trip, or to have the whole thing cancelled.</p>
<p>Now, those of you who know Philadelphia know that Central – the second-oldest public high school in the country, after Boston Latin – is a great school, but it sure isn’t in a great neighborhood. It’s in a part of North Philadelphia called Olney, and while Olney doesn’t look as bombed-out as the most depopulated parts of the city, its crime statistics are actually much higher, because it actually has people living, working, and going to school in it. Most of the kids at Central take public transportation to get there, and many of them take the subway and walk a good half mile to the school from the very, very urban subway stop. </p>
<p>The kids’ parents didn’t want to let them go to Vienna, because it was so dangerous. Trust me, 98% of the population of Vienna would have a heart attack if they found themselves at the subway station these kids used twice a day, every day. </p>
<p>The key is familiarity. When you know an area, and know its risks, you can evaluate them pretty accurately, and structure your behavior to minimize them. (Of course, sometimes you can’t minimize them enough, or you have to restrict your activities a lot in order to stay safe, and neither of those is a good thing.) When you don’t know the area, you are always on Defcon 5, and you wildly overestimate the degree of threat you face.</p>
<p>That’s what happens with Chicago, Penn, and lots of other places. They are fine – not perfect, but fine. But if you aren’t familiar with an urban landscape, or an urban landscape outside of a squeaky-clean business district, they can seem menacing and scary. And students there are at risk for petty crime now and then – purse snatchings, bike snatchings, getting panhandled. Nothing as bad as the risks suburban kids fact from drunk driving (themselves or others), but then suburban parents have other ways to cope with the drunk driving issue, and it doesn’t bother them as much, even if it should.</p>
