Street life is perhaps the biggest change I have seen in Vegas over the last few years. It used to be that people would take a cab from one casino to the next. The Strip was always crammed with traffic, but the sidewalks were deserted. Today, there are many people on the street, especially after dark, as in New York. The crowds have brought out large numbers of street vendors.
The Vegas Strip is the only place where I have ever seen someone riding a Segway down a public street.
It can be downright dangerous on those crowded sidewalks...one nudge and you're in the path of a bus.
A few years ago, wifey and I walked the strip from the Frontier all the way to Mandalay - beginning around 9am....the plan was to take a taxi back, but seeing how crowded Las Vegas Blvd was, we just crossed the street and casino hopped all the way back - we could track recognizable vehicles, and made better time (except for the breaks we'd take inside) than the traffic.
