Geography Pub Quiz for Post

Inspired by last night's waiter, who kept us busy with these all evening, I present you with four questions. Please answer without reference to Google, Wikipedia or other cheat-y mechanisms. (I admit we had to phone a friend to finish the last one but we managed the others on our own!)

Those who answer 3/4 or 4/4 correctly can choose to receive a postcard or a letter from me. Please indicate if you would like to receive post in your response.
