Address: 1405 Porter St, Frederick, MD 21702, USA

“Not the biggest or best for a military base, but it definitely has the best gas station on post. Guaranteed to be able to provide gas every 5 out of 6 visits. They have high end big screen TVs for sale, but only the cheap flashlights. Full sized liquor store too. Can't forget the essentials.”
