I sympathize with your concerns about accuracy. I tend to always want to write about places I've never been (or had brief glimpses of) because it's my way to travel (cheaply) and because I love research. But it's a huge problem sometimes--eg., the Boston State House--I've never been in it and a lot of my novel line takes place there. I have photos, floor plans, etc., but I still don't really know if you can access this hall from that door or how many strides it is from the State House to the Common. I need to visit; and yes, I'm trying to find out right now (for a different novel) what sort of birds might be migrating through southern Spain in spring (and when this spring should actually be). I'm glad your story found a good home; you should rest now.
