Dearest Grace...

Dearest Grace... is a holotape found on a dead wastelander (ref ID ) $$

Location
From Old Olney, travel east to the Red Rocket under the highway overpass; the one with the jack-knifed Nuka-Cola truck carrying the Quantum shipment. Take the road north past the three-way intersection. After passing the billboard, begin looking east. The corpse is between the standing and knocked over trees.

Alternatively, head northwest from Chaste Acres Dairy Farm to the Red Rocket. Once there, take the road north and then turn and take the first turn east. Follow the road until hitting a building with a blue car. Go to the car, and from there, face west at a tree. Go to that tree, go past it and keep heading west to another tree. The wastelander should be found dead under that tree and the other broken tree next to it.

Behind the scenes
This is a reference to Homer's Odyssey in which the main character goes on a long trek after the Trojan War.
