So-so reference
editAfter an extensive search (online), the only reference that I came up with was Pinchuck (2002). It's a travel book, which is not great, but has more intelligent things to say than some travel books I've seen. I decided that it was better than no reference at all. Hopefully someone can find a better one. Leschnei (talk) 15:46, 25 July 2016 (UTC)
