When I was getting my mail this evening, there was a young kid of maybe 10 years or so also getting his mail. He asked me what my Segway was called and how it worked. He said that it must "be in the world records for coolest thing" (something to that effect) and figured it "must be expensive." He wanted to walk alongside me. Clearly his parents never taught him to beware of tall men in black trenchcoats holding an umbrella while riding a Segway.
This is in contrast to most older people I've encountered, who generally seem to be somewhere between apprehensive and terrified when they see me. People on the Microsoft campus seem to be the main exception to that rule. I've only run into (figuratively, of course) a couple of kids while on my Segway... I haven't decided whether they are generally just not afraid of weird new transportation devices because they're used to new technology and dangerous methods of transportation, or whether it's just because kids are rarely as concerned for their own safety as adults are.
