Booking through vacation spots

Do you buy books while on vacation/holiday? Do you have favorite bookstores that you only get to visit while away on a trip? What/Where are they?

I take along books with me. I do not go book hunting while on a vacation. However, if I see a bookstore, I do go in. If I like something, I do buy. I do not buy the usual stuff. I go in for local historical facts or flora or fauna.

As I choose new places each time, I am not aware of any bookstores before hand. Many a times, I have found quaint bookstores hidden in corners. I love browsing in those.

Lately I find I am not much interested in reading while vacationing. I prefer to walk around exploring new places.
