This reminds me of when I got my first pair of glasses as a kid
(nearsighted). The ground seemed almost a foot farther away, though I've
never really noticed as much difference with later prescriptions, so this
could be partly due to a bad grind on the lenses.

Now that you mention it, Disney World did look a bit "smaller" than it did

the same ground, and I was free to wander off anywhere I wanted, too! ;-)
