Grayditch was a community on the outskirts of Washington DC. After more than 200 years of wasteland devastation and neglect, Grayditch was reduced to being the home for two families and a scientist with a special scientific project.
Two families consisting of seven friendly humans in total inhabited the settlement, until a scientist going by the name of Doctor Lesko turned up. Dr. Lesko sought to genetically modify the giant ants that had been ravaging the wasteland back to their pre-War size, however his experiments were botched and instead of shrinking the ants, he inadvertently gave them the ability to spew fire. The fire ants quickly infested the town and killed all but three of the town's residents. The only survivors were their creator Dr. Lesko, a young boy named Bryan Wilks and an unnamed fleeing resident.
The fire ants scattered about Grayditch number about 15 at any given point. They sometimes spawn behind the player in an area already cleared. After killing approximately 30 ants, they do not respawn above ground.
It is advisable to loot dead ants immediately if one intends to do so, as the ant corpses may disappear as new ants spawn.
Another survivor of Grayditch can be found in a random encounter. The survivor is not mentioned by Bryan, should you ask about the residents, but if spoken to, the location of Grayditch will be marked on your map. He will say that Grayditch is burning to the ground.
Upon first speaking to Bryan Wilks, he references his playmate Will Brandice. However, one of William Brandice's computerized journal entries references Frank, rather than a son named Will: 3 computer files reference William's children. 4-02-2277 and 10-02-2276 reference Will, while 2-24-2277 mistakenly says Frank.
Bryan Wilks will be found in the town or the surrounding area before the player first encounters him. He will usually approach the player, but he can get frozen in a given spot due to a glitch. If the player agrees to help him, he will proceed to the Pulowski Preservation shelter by the diner. Once the ants are gone, he will return to the Wilks' house.
Proceed due south from the Pulowski Preservation shelter that Bryan Wilks hides in during Those!. Look for the building on the right above you with the Enclave poster on it. Go past the barricade and up the hill to the rear of this building (two cars in parking lot). The door that is labeled "Outpost" leads to two rooms with a super mutant and an intelligent ghoul with decent loot including a scoped .44 magnum.
Although it's been overrun by fire ants, high level players might encounter radscorpions and raiders in the area.
On William Brandice's Terminal, it shows that he's been traveling from Navarro for quite a while.
Behind Dot's Diner, there is a trash bin with a very hard lock.
The key to this container can be acquired from Bryan Wilkes through a speech check.
