Pat Davids here. Happy Spring.
As it turns out, sitting in the library will only get you so far when it comes to writing realistically about something you aren't familiar with. Take the Amish. There's still a lot I don't know about the Amish even after 12 books in my Brides of Amish Country series. Their culture is so diverse that what works for an Amish romance set in Ohio won't necessarily work for a story set in Pennsylvania.
