When Kathryn and I make our regular road trips to Las Vegas, we typically leave Phoenix after work Friday, in the middle of the afternoon. If all goes well, we arrive in Las Vegas in the early evening. Usually we arrive without any specific plans, and we just sort of wing it. There's no shortage of things to do there, but we often feel like we could have used our arrival evening more wisely. So last week, before leaving Phoenix, I decided to make a dinner reservation for 8:30.
