(Las Vegas, NV) — Local cab companies have reason to smile these days. New figures from the state Taxicab Authority shows cab trips in June were up more than 10% from a year ago. All of the valley’s 16 cab services showed increases last month. One event that helped the bottom line was the Electronic Daisy Carnival. The authority granted extra cabs for the electronic music festival at the Las Vegas Motor Speedway, and it paid off as concert-goers opted for taxis due to heavy traffic for private cars.
