Don Carter State Park in North Hall County wants area businesses to cash in on the tourism it’s generating from its spot off Lake Lanier. “One of the benefits of having a state park in your community is all the business that it generates for the local (merchants),” park Manager Will Wagner said. The Georgia Department of Natural Resources and Lake Lanier Convention & Visitors Bureau are holding a free seminar, “Doing Business With Don Carter State Park,” set for 10 a.m. to noon March 5 at the Hall County Government Center, 2875 Browns Bridge Road.
