I know I have to be right about the basic facts of the era and get the ambiance right, but what about things like the weather? I mean, other than knowing that the place usually gets hot in the summer or something, do I have to know that on February 9, 1938, in Munich, Germany, there was a thunder storm? Or is that overkill? Now, I can find out, since the time period I'm looking at is fairly recent, but I don't want to be so bogged down on things like that that I lose perspective on the whole story. But in the finished product, should I try to find out trivial details like that, or should I move on? Likewise, I'm having trouble finding a way to include historical information in my actual narrative. It feels artificial when I drop in random historical information. I end up mentioning things in dialog or thought or radio broadcasts, but does anyone have tips for finding the proper balance between historical information and narrative? Because infusing them seamlessly is very difficult!
