The great feature of gallery crawling is getting to cover so many streets and alleyways. I have two of the large 20x30 inch gallery guides - one opened and folded so one side shows and the other opened and folded to the other side. So I can look at the map on the one side and read the addresses on the other without unfolding and flipping. Couple that with a very good focal London pocket map published by Knopf and my innate ability to find my way and efficiently construct serpentine walks and I can knock off 39 galleries just this afternoon. Many galleries are upstairs and in obscure places with poor signage that without fortitude would for all intents be non-existent. My reward is to see “behind” and “between”. And a huge reward are the focused and intense conversations shared with the dealers who are locked in their daily world; happy to talk to the foreigner with stories of his own.
