Coming down the Mountain there was a Brewery on the Hill

Must be Pottstown

And how do you get from the State Highway to the Brewery?
use your nose...

Don't know if you can read the top of the building, but this is across the street from the brewery, it says "Ice Cream" and "Dairy Products"

The communication system batteries had just reached their limits, all talking is over, suddenly you see something you want a photo of, the other bike is 5 lengths ahead of you, down hill, heading back to the highway, what do you do?

Simple, blow the horn, and take off to the photo op. The other bike will either turn around and catch you, or, you spend the rest of the day trying to figure out how to get to the destination without a map or a name of the place.

He made the turn.
