Sherman Park Grocery Store needs our help, neighbors! The grocer on Fond du Lac Avenue at Sherman Boulevard is at risk of going out of business. It opened four years ago selling fresh fruits and vegetables and affordable groceries, but no alcohol or to***co. It remains true to that vision today. The owners are also members of the community, as well as loyal and active supporters of SPCA. Now it's up to us to show them our appreciation by visiting their store and spending some money.

Our mission is to connect neighborhoods with community leaders., but this was interesting that someone is going to talk about legislation that most of us know nothing about or what's in it. Share this with your neighbors and your friends and family. Would be interesting on how this bill will impact our families
