Looking for an MLK Day of Service Volunteer Opportunity for a Group

Hi,

I'm trying to plan a volunteering event for group of ~20 people.

• In Detroit proper or an organization that serves Detroit residents
• Not food-related
• Not a religious organization
• Not outside [[okay, this is just because I am a baby, so I can yield on this)

Any suggestions?

Habitat for Humanity? Maybe an event like the Belle Isle spring cleanups - outside but nice weather.

I'm looking specifically for MLK Day.
