Use them. Jessy, the owner, will take of you. In my case I had a couple of trips where he picked me up at 6am and dropped me off at a trailhead several miles away, so I could hike back to my car. He or one of his drivers can drive you to Reno Airport or as far as Mammoth. Unusual local law states a cab ride that starts and ends in Nevada can only be run by one company - if you're near the casinos, just walk a couple blocks to California and Crown Taxi can pick you up, and I think it's worth it. If you have questions, go their website and email - Jessy was very quick to reply.
