Driving vs. Flying to Las Vegas

Driving vs. flying to Las Vegas. Dealing with traffic vs. dealing with airport security. The open road vs. the pressurized cabin. Hmm, what to do? You can sometimes eliminate an option right away. For instance, if you're going to Sin City for a long weekend and you live in New Jersey, you're flying. But say you live in Phoenix, your best friend forever decides to get married the next day in a Vegas chapel and you absolutely, positively have to be there, throw an overnight bag in the trunk and hit the highway. If you could go either way, you'll need to weigh all the factors and decide which is the best for your particular situation.
