Four basic groups living in Northwestern Montgomery County Pennsylvania. Original farmers. Italian Americans from S. Philly. Hippies who grow marijuana. Ordinary folks who had no idea what they got into.

1. Original mostly German American farmers. Great History: General Peter Gabriel Muhlenberg, eldest son of Rev. Henry Melchior Muhlenberg, was born at Trappe October 1, 1746. 
2. Italian Americans from South Philadelphia who gradually moved along Ridge Pike to the Collegeville/Skippack area. Ask around Skippack Village. Almost every business there has a South Philly counterpart.
3. Hippies with expertise in marijuana growing moved to the Limerick/Spring Mt. area when they were forced to leave South Street because of the proposed Cross Town Expressway. South Street is still there. The Cross Town Expressway follows Spring Garden St.
4. The “Newcomers.” Rt. 422 was built and thousands of people moved to Collegeville, Limerick, Skippack, Lower Frederick area not realizing that many township officials got high every night. And that a little bit of the South Philly mob came with the people from South Philly. 

I lived near a man with a house and barn on Mine Hill Rd. In Schwenksville, PA. I could see his house from my bedroom window. Later I read that his barn was a huge marijuana growing operation. He burned the chaff in his home’s fireplace. There was a downdraft weather phenomena. The smoke went along the ground instead of up. The entire town of Schwenksville smelled marijuana. He was arrested. I call the Limerick, Lower Frederick, Spring Mt. area "Emerald Triangle East." 

The Bucky Fuller geodesic homes in Limerick Township PA is one of the many concepts brought into the area by people moving from South St. in Philly.

The people there are very nice mostly mellow people. But no way is it ordinary suburban style living.

I like the CAPPICOLA at the Italian Market in Skippack PA

Cappicola with sharp provolone tomato, red onion, sweet roasted red peppers, oil, balsamic vinegar, parmesan, and oregano - $8.50 

PS
I forgot one subset of people, not large enough in number for a group but significant for the potential for mayhem.  The skinhead/KKK. 

In spite of the construction of the Perkiomen Trail they still have cross lighting ceremonies along the Perkiomen Creek. Not exactly "Deliverance" but it's a little scary finding Nazi skinheads while fishing. 

A woman with 2 children living in a row home in Schwenksville called me when I was a planning commission member of Lower Frederick. I don't know why she picked me to call. She told me that 3 skinheads lived next door. She felt threatened. She was aware they didn't pay rent & they sold drugs. All I did was let the Mayor of Schwenksville know about it. The problem was solved. 

Around the same time some skinheads were arrested for bank robbery.
