How do we know that the summer’s almost over? The final 2011 Baltimore Avenue Dollar Stroll will take place this Thursday, Sept. 1. Yes, the fourth and the final one this year. So, don’t miss the chance to enjoy $1 deals again and say goodbye to this event until the next summer.

We hear that nearly 20 businesses, vendors and food trucks will participate in the final Dollar Stroll, so look out for new participants.

The stroll will start as usual at 5:30 p.m. (it’s not a bad idea to come early) and will go on until 8:30 p.m. Apart from the vendors, there will be live music and street performances as well. And, as always, there will be copies of the free West Philly Mix Tape download card available for pick-up. If you haven’t got one, stop by the University City District table in front of Calvary Church (48^th and Baltimore).

The last Sustainable Saturday will take place September 17. Stay tuned for more information.

A group of West Philly youths have decided: If the people can’t get to fresh fruits and vegetables, they’re going to get the fresh fruits and vegetables to the people.

Starting tomorrow the Youth Urban Mobile Market (YUMM) will begin delivering fresh produce from 52nd to 60th Streets in a bicycle-driven cart. The cart will launch on Friday at the first ever Youth Growers Market at Malcolm X. Park (51st and Pine Streets) from 5 p.m. to 7 p.m.  The YUMM cart will pedal the neighborhoods four times weekly, helping relieve the dearth of fresh food in many parts of West Philly.

The cart and tomorrow’s market are staffed by young folks from the Agatston Urban Nutrition Initiative, which is part of the University of Pennsylvania’s Netter Center for Community Partnerships. Students from a number of area schools are involved, including: Martin Luther King High School’s “Seeds for Learning;” Saul High School’s “Henry Got Crops;” the School of the Future; Pepper Middle School; the Philadelphia Urban Food and Fitness Alliance; Earth Keepers; and Walnut Hill Farm.

If things go as planned a lot more people in Philadelphia will see mobile fruit and vegetable carts around the city. The YUMM cart is the first of the City’s “Healthy Carts” program. Twenty carts are planned to begin operating in low-income neighborhoods in 2011-2012 as part of the “Food Fit Philly” program.
