D.B. Technical High School

D.B. Technical High School is a former Catholic High School within Boston in the Commonwealth in Fallout 4. This location is east of Diamond City and south of Combat Zone.

Layout
The are three levels within the main section of the building with various raiders filling the halls and rooms. There are the various traps such as bottlecap mines and a moderate level machine gun turret along with the raiders.

Once through the main section and down to the basement level, there is quite a bit of notable loot here.

The raider's boss, Bosco, in his terminal notes appears to be suffering from rabies contracted after being bit on the hand by one the raider's dogs. The notes show is slipping into hydrophobia and his rampage in killing his crew for the slightest offenses. Bosco is wearing the mascot costumes' headpiece.

Just to the east of the swimming pool room, there is a door to the generator room. This leads down to a small metro station initially filled with raiders. Once they are dealt with, the room loops around to another area with five to six bloodbugs. Depending on your level, these may range from just hatchlings to red widow bloodbugs.

If you start at the front door of the school, this path finishes up at the Medical Center metro location.
