I'm obsessed with attention to detail. I've talked about it before, and how that obsession is a factor in my love for the Disney parks.
Last time I was in Disneyland, I noticed that all the manhole covers in the park are customized with Disneyland written on them.
Now, most people probably do not notice this, but it's just one of the many little factors that contributes to why Disneyland as a whole is the happiest place on earth.
Most other cities also practice in the customization of man holes, putting the city name or emblem on them. When Disneyland goes ahead and does it, it helps relay the feeling that you're not just in an amusement park, but a different city, a different time, or a different world.
It's those little things that make the big thing the best thing.
