It's a good bet the riff raff from Maine is really from Mass. They don't make it in Mass, so come to Maine NH and VT to be somebody. They don't cut that idea here either.
I was in town at apx the same times you were in that area, and found traffic a little faster than the posted limits.
You must remember and take into account that this is Christmass vacation week, with super high traffic flows, and more so in the area of walley world, since the riff raff is returning all the chinese junk they broke since Christmass day. The flow will ebb after this coming New Years Eve Weekend.
I am just down the road 15 miles south from the entrance to the Kanc. The little black bubble car that passed me at the Brett School was from Mass.
NH is not free from road rage either. With every Tom, Dick, and Harry and his spouse all from 'away' they bring things like crime, and road rage with them.
This sort of thing was un-heard of in NH pre 1985. It has been a good number of years now, since 1985, and NH is no longer that Currier and Ives place people from away think it is.
People from away bring their baggage with them when they move here.
N Conway isn't a quaint little NH village anymore, and it hasn't been since the airport was turned into Settlers Green. N Conway is the Sodom and Gomorrah of NH.
You get riff raff in that element anywhere on earth. Getting a car battery at walley world 2 summers back for a friend, I encountered the walking dead at walley world. I don't know what else to call these kids all dressed in black with dark purple make up (boys too) and black painted finger nails, but they were not good looking people IMO.
Assuming you drove into the villiage area where Horse feathers is, and Zeek's, the train station, all the way from the Rt's 302 and 16 USED to be a scenic vista looking over to Catherdral Ledge and White Horse Ledge , up the valley towards the Presidential Range.
With your own eyes you saw that is gone.
Living here means you learn traffic flow. On a Friday night you want to be south bound and return some other way. On a Sunday night you want to be North bound and return some other way.
If yer still around shoot me a dm and we can meet over a coffee somewhere, or you can come visit here if you prefer. I do have plans for New Years Eve, out in the woods. If you want to go there bring warm gear to have. It is at a house, and there will be a large bonfire, set up to be dry since last Spring. Wholesome folks in the middle of no where. You can be my guest.
Depending on age you might call me uncle, or I might call you that.
