My sister and BIL came to visit one year when I was then living in Silicon Valley (San Jose, CA). We went to have dinner with a sibling one evening in an area of town known as Quincy Oaks. On the way back, they were relying on their brand-new GPS device to find the best way back to the hotel, when I suddenly realized we were going to pass directly through the area between the Eastridge Mall and the Story and King crossroads (for those of you out of town, that had become as of the early eighties the crown of gang-ruled territories).
I volubly (and vociferously) forced then to backtrack and find a highway to the side that would get us past the area until we could have a direct shot back to our destination that would not entail any travel through those areas. They were markedly annoyed, but after I explained later what exactly they might have gotten into, they grudgingly admitted I might have been right in the end.
Pfft! Tourists!
the same technology can help protect us against getting mugged in dangerous neighborhoods....
