I got the CHR one. You should probably google up a video on how to get the bobbleheads and watch it because its actually locked behind a questline, rather than being something you can just travel to to pick up.So what has people's success with bobblehead hunting been like? No spoilers since the location info is available on the wiki,Fallout 4 Map | Interactive Map of Fallout 4 Locationsetc. Just curious about "was easy" or "got my ass kicked repeatedly and gave up" type info.
ST = about to go try to get it now
PE = trivial
EN = unknown, far away and really don't care about EN
CH = gave up for now
IN = pretty easy even before Diamond City
AG = was going to wait but Hatorade made it sound fairly simple to get
LK = too far away at the moment
Not real concerned about the others, and I only looked up spoilers for SPECIAL ones that are stopping me from taking perks. Repair was simple enough to find, as it's on the main quest path. Pretty easy to miss though unless you explore thoroughly or look it up.
Also got luck (trivial with radaway and radx) and agi. I was rushing the agi one, theres a lot of mobs there but I just ran past them while my companion distracted them for the most part.
