My son is driving up to D.C. to spend 6 weeks helping his sister out (a paid job). He has never taken a long road trip before by himself, so I thought it would be nice to get some common sense suggestions regarding routes, maximum drive hours per day, the best way to approach D.C. and safety concerns that perhaps are more recent. It's going to be a fun but rather daunting experience for him, I think. When I was his age, I thought nothing of driving 13 hours in my VW Bug (by myself). But times have changed. And now that I'm a Mom....I realize everything that can go wrong! One other question is....having a car in D.C. Is it a good thing? (they have parking for the car and they can go exploring on the weekends out to VA, etc.) I have always appreciated the information and advice people are so willing to share here at RTA. Thanks!
