Here, you'll find Granma operating a trading post inside a rundown gas station. She'll sell the player a number of edibles, chems and medical items, along with the Elixir of Life, a unique drink that permanently adds +1 to Endurance and +17 Hit Points.
Any items you leave on the floor of this map will respawn every time you visit the map. (fixed in 1.27)
