The neighborhood watch groups 48th Street Neighbors and Me-Lo Town Watch will jointly host another “porch hop” on August 4 as a way for neighbors to get to know each other better.

The hop will run from 5 p.m. to 8 p.m. rain or shine. So far 11 porches spread across both sides of Baltimore Avenue are on the itinerary (see the map below). Snacks and drinks will likely be provided on each porch, but it never hurts to bring along some of your own, including some wine or beer.

Here are some more details:

The legendary bicycle store at 4311 Lancaster Avenue is reopening under new ownership and inviting folks to their Grand Reopening Extravaganza, titled Dances with Wolves, this Saturday, July 28, from 2 p.m. to 2 a.m.Wolff Cycles store was recently purchased by West Philly’s Firehouse Bicycles (50th & Baltimore) and renamed to Wolf Cycles (with 50% less F). The shop has been in operation since the 1930’s.

The grand reopening celebration is free and open to the public. It will feature workshops, a bike ride, catered food and beer and an outdoor movie screening. Also there will be music by live DJ’s and raffle all day. Costumes are encouraged. Here are more details:
