Life around the Intrepid has regressed, but not by much. The Intrepid has been gutted of most useful equipment, and even some bulkheads have been hauled out and made into a makeshift wall with the Intrepid making up part of the wall with its bulk. Atop the wall are stationed sentries with weapons cleaned and restored from the Intrepid's own armory, mostly M16s using 5.56mm rounds. Raids of gunshops and trade with merchants have left them well stocked on both 5.56mm and the less powerful but more plentiful .223 rounds. Most of the hunting parties who go out trying to find meat use the .223 rounds. Their goals are to find some of the local critters to domesticate, but for now the lush wildlife that has kept their meat stocks high. Most of the food comes from the crops being grown inside the walls.
Most people wear clothes from 100 years ago, maintained with scraps. It's not uncommon to see military uniforms, suits, dresses, and assorted other clothes. A few cars have been maintained, though they're only used in emergencies such as when supplies get critically short and they need to be reinforced from a settlement in the south. Every few weeks or so, a convoy arrives made up of trucks salvaged from the wreckage carrying goods. The computers aboard the Intrepid make a good trade, and so the merchants are often eager to trade ammunition. Another major trade item is the whiskey made from the grown crops and the oil pressed from crops. The oil is used as a fuel for diesel engines, which can burn almost anything, so traders often stop at the Intrepid to refuel before moving on to other posts.
The closest major settlement is Camp Dawson, a US Army base in West Virginia, which keeps the Intrepid supplied with ammunition in exchange for spare parts. Camp Dawson is just one of several facilities in a chain forming what's left of the United States Military Command. Resources are still scarce, but over time they've managed to form a network that keeps the other bases informed and a haven for rebuilding. They've begun a project to build a road to Intrepid with gravel to make it easier to get in and out, especially during wet weather, but so far progress has been slow. Negotiations are in the works to make the Intrepid part of Military Command and sending a detachment of soldiers to garrison the Intrepid.
