What is the easiest way to get from McCarran rental to Main Street Station? I've looked at Google maps and it wants to take me on I-15. While I'm not opposed to highways, I'd like to take some side streets so I can make a grocery stop on the way. I have to get Pepsi and maybe a bottle of Whiskey along the way. I'd like to get some fruit (apple, banana or such). I'll also need some bug spray and Suntan lotion. Any thoughts?
