Reading Rory's account of his first real trip to Las Vegas was very enjoyable. It brings back many fond memories of the town.
He mentions several times the scale of The Strip. It's amazing. As I commented to him, it's like the Grand Canyon: you just can't understand until you see it up close and in person. The hotels are huge, but since they all are, you don't realize it. You start walking down the strip and see your destination up ahead - “no big deal,” you think, “it's not that far.” Then, an half-hour later, it's still up ahead.
Rory gives some good advice for visitors to Vegas: “The trick... is to not take the city at all seriously.” You can then enjoy it for what it is and not be too freaked out.
