Hundreds of trips to the US, never. Have sampled the hobby in the UK, France, Spain, Italy, Aus etc. But have never and will never risk it in the good old US and A. The Christian taliban still has too much influence there, and furthermore it is much more expensive.
However when flying to the US, I make sure to book an early am flight so I can justify a hotel stay in T.O. the night before and arrange a meeting with one of my faves from the 6ix.
