Have you been on the road a lot this week? The traffic is some of the worst I've ever seen! Why?

It was so bad late one afternoon from Route One in Falmouth (all north bound) I couldn't help notice heading into Portland. The traffic was backed up from Route One in Falmouth damn near to the exit off 295! Then 295 North was insane...

 

The traffic northbound was backed up for miles. This is from around Tukey's Bridge in Portland headed south. Traffic was backed up for as far as the eye could see....headed north.

What is going on? Everywhere traffic in Maine is insane! I know, I know...tourists - but has their been an explosion in the tourism industry? Am I crazy or have you noticed that traffic is extra heavy these last few summer days?
