The first thing you should know is that every event, activity and meeting is an opportunity to promote your business. Along with business events, community activities are a great way to network. It's not enough just to show up, though. To get results, you need to make sure people remember you and your product or service. You don't have to spend a fortune.
Politicians do it.
So, join in. Meet your neighbors. Share your skills. Lend a hand. Help your community and promote your business at the same time.
