Thanks Horseluvr, Cataholic, Ramanth and Delidog!

Delidog, I hadn't really noticed what kind of uniforms they were.
They went by us pretty fast and it was raining so some of the photos are dark and not that good.
I'm not even sure what the banner they are carrying says.
Yes, Vermont is in Yankee country, any farther north and you'd be in Canada!
The photos were from Memorial Day so the theme was for remembering past soldiers if that helps explain anything.
