Ride starts/ends at Weavers Way Co-Op in East Mt. Airy (1011 E. Washington Lane, Philadelphia)
$25 for Weavers Way members, $28 for non-members, and $30 same-day registration
The annual Weavers Way trek covers a large swath of the city -- including Kensington, South Philly, West Philly, Germantown and Roxborough, including Urban Girl Farm, Methodist Home, Marathon, Refugee Community Farm, and Wyck House.

Web Start Women July Startluck Picnic
7 p.m., Sunday, July 24
Mario Lanza Park (Queen St., between 2nd and 3rd, Philadelphia)
Free admission
Geeky gals unite: Web Start Women was launched locally in April by Penn web design lecturer Susan Buck and Nicole Noll, a soon-to-be fellow in the Harvard University psychology department, to encourage women to pursue programming, development and tech startups -- still mostly the domain of men. Now 100 members strong, the group routinely holds workshops, like its Photoshop for Web Developers class on July 25.
