Locations
Ulysses Log Y-17.16 - In The Crows' Nest, inside the top of the ruined buildings next to a bedroll. NOTE: It is unknown if detonating the warhead at the base of the buildings makes the holotape unreachable. Ulysses Log Y-17.21 - Directly south of the Collapsed Overpass Tunnel Entrance. Behind a hard locked gate. Ulysses Log Y-17.22 - Just beyond the High Road, once you reach the end, you should see a truck sticking out underneath an overpass. Jump up the rocks to get to the truck, turn right. You should see smoke from a campfire. The holotape is directly south of the campfire, leaning against a rock wall.
