New York
Spent a week there earlier this year. I'd been wanting to go for a long time and it didn't disappoint the sheer pace of it, the neighbourhoods all having completely different feels, the food being genuinely great everywhere. Did more then one run in central park it was that good.
Asia last summer was the big one Japan, South Korea, Taiwan, Hong Kong, and Singapore across about five weeks. Japan was probably my favourite the bullet train and spring baths wher so nice.
Elsewhere: Budapest, Vienna, Slovakia for a few days each. Budapest especially the cruse and the bars.
