There was a similar thread within the past few weeks http://www.wrongplanet.net/postt171891.html , but in case this one doesn't get merged, here's my post there:
This is definitely one thing where I'm just about opposite of most other Aspies and those with HFA... People say I have a "map in my head". I can "see" the whole city of Los Angeles and surrounding areas, and I know just about every little canyon shortcut, and even most of the fire roads through the Santa Monica Mountains. That city will confuse even seasoned taxicab drivers who grew up there. I would say it's virtually impossible for me ever to get "lost". I've driven all over the USA, alone and with my wife, and never felt lost. Dallas is still new to me, but I got a decent image of the overall Dallas map in my head almost right away. I go to Reno once a year for the Hot August Nights car show, and I didn't even try to memorize Reno, Sparks and Lake Tahoe, but it happened by default. Even Philadelphia, where I have not set foot since I was 10 years old in 1977, I still retain a basic map of it. I don't know how/why I'm this way, but it sure helps when I'm going someplace.
One thing that WILL get me disoriented, is huge parking lots such as Disneyland or a major shopping mall with many entrances. If I don't pay attention to a number or letter on a post nearby, or memorize that I'm "x rows east of x store", etc., I will forget where I parked, and have to think hard, and maybe make a couple hit & miss passes to find the car.
I'm not much into hiking or walking in the forest, but I have done it many times, and never worried about staying on trails, or remembering landmarks. I can just "feel" where I am, and I always am conscious of where the sun (or stars/moon) are in the sky, relative to the direction I'm facing, and I automatically compensate for how they move as the time goes on. I've never been able to comprehend how any hiker could "walk in giant circles" and stay lost in a small area. I just don't get it. But I respect it, and of course would not want to be in that position nor wish it on anyone. When I was 8,9, and 10 years old, my family went to Yosemite every summer. I used to like to go for long walks alone in the woods, and I never felt lost or scared. I never was late to come back, and if I took a wrong turn, or if I saw a danger and deliberately altered course, I'd easily still know where I was, and could get back.
