I love the TT, wish I could have gone this year, the atmosphere must be amazing (not that it isn't any other year).
I've been three times, and it's always right up there with the best experiences of my life, even the year when we had to come home early 'coz we'd spent all our money to keep a mate out of jail when he got clocked coming down off the mountain at 162mph in a 60 limit...
Everyone should go at least once, it's fantastic.
