The Pittsburgh Urban Magnet Project, or PUMP, is planning a summer's worth of concerts, events and activities in Market Square on Fridays to keep people Downtown after work.

PUMP developed "Stay & Play Fridays" after a survey of members last year found that nearly 60 percent felt the revitalization of Downtown should be the group's most important issue in 2008.

Dunkin' Donuts, which is to open a store in Market Square June 30, will partner with PUMP to sponsor "Stay & Play Fridays" from May 23 to Aug. 1.

PUMP believes the after-work activities will help merchants in Market Square and increase vibrancy Downtown.

"There is a definite need for affordable Downtown housing, cheaper parking and a more upbeat urban core that stays open after 5 p.m., and the survey results demonstrated 'Stay & Play Fridays' as something we have to do," PUMP Executive Director Erin Molchany said.

Details will be announced in coming weeks.
