I've been writing for a long time so researching has been fun to say the least.
I've gone into our local Native American Store where the owner was a great source of information when researching Native American History. My children knew I would be there for hours if I said, "Let's run in real quick to the Native American Shop." There was no real quick on that one.
Crazy things I've done...
I've brewed white willow bark to capture the aroma of the room while writing a scene in Come Home With Me. I often do that with herbs if I am working on a healing scene. Like Dragon's Blood, from Into the Darkness. Dragon's Blood is my all time favorite scent, so I often burn that, or put on the oil while I am writing. Especially when I was working on Into the Darkness.
I use 100+ year old encyclopedias to research historical points in history, and when working on Passionate Pursuit, I had the old maps in those encyclopedias spread out across the table to outline my path for the cattle drive.
I would have to say the craziest thing though was the afternoon I was writing a shower scene in Never Let Me Go and I could not for the life of me think of the name of a shower scrunchy. Well, I hollered upstairs to tell my youngest son we have to run into the store. We drove into town and hit up three stores before I found out they were just called scrunchies :) Of course, before I did all of that running I spent some time calling around to friends to see if they knew the name of it, LOL.. Yeah, the silly things that will halt writing in its tracks...
