I'll second what everybody else has said. Do it while you're young.

Make sure that the travel is organized by YOURSELF and not by a corporate travel agent that sucks. THIS is what has made it possible for me to do it for nearly 10 years without losing my mind. Also check into the company's "alternate travel destination" policies. Some companies allow it, some don't.

Some companies allow it provided that the plane ticket is about the same price. E.g., if it costs 400$ to go ORD to ATL r/t, and you want to go to LAX for the wk-end, as long as it's about 400$, you can go. Some companies don't allow that at all.

And if possible... try to find a 4-day-a-week gig. Being gone Sunday-Friday is brutal on your social activities.
