Freight, not tourism, runs Macon's fuel market most of the year - the I-75/I-16 interchange (one of the busiest freight crossroads in the Southeast, currently mid-overhaul in a $500 million GDOT project), Norfolk Southern's Brosnan Yard rail hub, and a nearby Amazon fulfillment center all push heavy commercial diesel volume through stations spanning Vineville, Ingleside, and the historic Pleasant Hill district out to East Macon, Payne, and Warner Robins. Robins Air Force Base, Georgia's largest industrial employer with more than 25,000 workers, adds steady fleet-card and government fueling from just down the road. Mercer University's roughly 9,000 students bring a different, high-frequency demand pattern closer to campus, and the ten-day International Cherry Blossom Festival each March briefly flips the whole picture into one of the state's biggest predictable tourism spikes. There's no income-tax break here - Georgia's motor fuel excise, prepaid local fuel tax, and roughly 8% Macon-Bibb sales tax all apply, on top of a consolidated city-county government structure most Georgia cities don't share.
