As more people use smartphones to look up business addresses, hours and phone numbers, businesses without an online presence may be at a disadvantage. With the launch of Google's "Let's Put Our Cities on the Map" campaign, the search engine is looking to help businesses across the country have a presence on Google Search and Maps. When people can find information about businesses in their local community, it makes the community stronger. Bring your laptop and Let's Put Perry Hall and White Marsh on the Map! Sponsored by the Perry Hall White Marsh Business Association. Registration required. For questions and to register, visit www.phwmba.org.
