As residents of Riverside, we should all think about where we shop and what happens to our money after it hits the cash register. When we shop and eat at local businesses, we invest positively in our own community.
Studies show that almost seventy percent of money spent at a local business stays local, compared to about thirty percent spent at a national chain. Local businesses will more likely use community businesses themselves: banks, services, local crafts, and farms. It is a kind of domino effect.
In addition, buying items made locally means we are getting something unique. Eating at a locally owned restaurant means our neighbor planned the menu. You can't discount that one-of-a-kind feeling!
