Hello All, I'm Jason Griffing and I work along with César here at Expomuseum. I am an Expo fanatic and have attended 15 World Expos since my first one in Knoxville Tennessee USA in 1982. I have an interest not only attending Expos but also visiting Expo sites after they have ended to see how the sites develop and/or to see what remains...even ones from earlier in the last century. I also have an interest in architecture and design which is another reason Expos call out to me. I look forward to meeting all of you here and sharing our enthusiasm about Expos!
