Heather while driving encountered Alan Hodgkins. He stopped his vehicle to look at her.

From Heather:

I was heading into Boston and about to get on Route 2 which requires me to go under an overpass. As I went under it Al turned under it coming in the opposite direction. I didn’t know his route extended out that far.

I think he saw me and then it seemed that he stopped under the bridge to watch me until I left. I didn’t have my phone out and I didn’t stick around to see what happened next. A car let me make the turn and I left.
