Just nipped into The Works to see if they had any books on Thailand. No books but I picked up a map. Bargain at 99p. When I got to the til they told me it was a BOGOF so I went and picked up another map of Thailand. That's one for me and one for Dad for the grand sum of 99p. If that's not a bargain I don't know what is!
I doubt it will be any good for navigating but will be useful to see where Dad is and where he is heading on his trip.
