Thoughts on my travel plan please (driving straight through): Leaving Binghamton, NY on a Friday afternoon, 5:30 PM, late October. Prefered route: 81 to Harrisburg, 15 to Frederick, 270-495-95 past DC and all the way to I-4. Couple questions: How will traffic be at DC (I'm guessing we'll arrive at the 270-495 interchange approx 10PM)? Any other traffic issues I should consider? Harrisburg? Jackonsville (should hit approx 9-10 am Sat morning? Thanks
