Here’s a great chance to learn more about the historic West Philly neighborhood of Powelton Village. On Saturday, Oct. 1., the Powelton Village Civic Association is organizing a 4-hour-long tour which will guide you through the neighborhood’s tree-lined streets and will introduce you to its beautiful homes and gardens and their history.

The tour will begin at 11:00 a.m. with the starting point and check-in at 3501 Baring Street (four blocks north of Market). Tickets are $15 for adults and $10 for seniors and students. Check the flyer for more information. All questions should be addressed to: president [at] poweltonvillage.org

St. Francis de Sales (47th & Windsor) is organizing a flea market tomorrow, from 9 a.m. to 4 p.m.  There will also be a sidewalk sale at the corner of 43rd and Osage from 9 a.m. to 3 p.m. Bargains, lots of useful stuff, and… free cookies! See the flyers below for more information.

Dock Street Brewery will host the only Philadelphia’s screening of the new documentary Urban Roots on Tuesday, Sept. 20, at 8:30 p.m. The film, produced by Tree Media, tells the story of the urban farming phenomenon in Detroit.

The film follows a group of local farmers who are working to turn a troubled industrial city into a model of local farming and sustainability. It is a timely and inspiring film that shows hope for us all in a sustainable and prosperous future after the end of the industrial age.

The screening is free and Dock Street is donating $1 per beer sold during the screening to the Tree Media Foundation which works to put farms in local schools. The film will be screened on the new and improved projector screen. It is recommended that you arrive early to secure a seat.

Here’s a trailer:
