I once won a fair bit of cash in a Ladbrokes in Utrecht. On that same trip with my Mum I bought a double CD of the best of Quicksilver Messenger Service. I was particularly impressed with the 'dryed out' canals which housed many bars, eateries plus clothes and household goodies shops. F****n' simpler times for this auld capitalist hippy!
I've been to Hawaii, not sure if that constitutes as far west or as far east as you can get though. I cycled past Carlos Santana's house apparently.
