Like the migratory patterns of Arctic Terns,the travel patterns of the Doors crowd are a perennial mystery.All we know is that people register later every time we do a Doors event. (At Doors 7 in Amsterdam, we sold a third of our tickets in the last couple of weeks). Now, with just four weeks to go before Doors 8 begins, we know that more people are thinking about coming, than have yet decided. Please note: you cannot register for Doors 8 by SMS, and we do not advise trying to obtain an India visa using a mobile phone. Be modern: don’t leave it too late.
