It has been 39 years since the launch of Dally in the Alley in the Cass Corridor, one of Detroit's hipper festivals, that has tried to maintain that underground, off-the-beaten path feel.
But its growing popularity has raised some concerns among organizers, writes Chris Ehrmann in Crain's Detroit Business. The festival is Saturday from 11 a.m. to 11 p.m.

This year's poster is designed by Evan Condron.
Crain's reports:
Last year, an estimated 50,000 to 60,000 people attended the festival — the largest crowd in Dally history. This year, with less promotion and changes in the format in an effort to bring Dally back to its roots of a smaller Detroit-centered festival, organizers are expecting around 40,000 to 50,000.
This year, organizers did not issue a press release and turned down some potentially sponsorship offers.
"One of the things this year is going back to the fundamentals (of Dally)" Steve Germain said. "It's a community street fair, and ultimately we want to benefit the neighborhood have a welcoming event for Wayne State students."
Proceeds support North Cass projects that improve the quality of life for people who live and work there, Dally's site says.
Cass Corridor, aka Midtown, where the festival is held, is changing as more high-end restaurants and businesses pop up. Longtime residents are hit by rising rents.
