Jon Gault has up an article on how much he loved Zurich. It's the one meet I've always wanted to go to.

So that begs the question what is the favorite track meet you've been to?
For me, if I had to pick one semi-regular event, I'd say go to Olympic Trials. Great atmosphere and drama, but that isn't an annual meet.
Annual meet- Pre has to be #1 for me.
I really liked the first two editions of World Relays in Bahamas. Crowd gets into it. Have no idea how it was this year.
For one off events, the Pan Am Games in 2003 were unbelievable when Felix Sanchez won the 400m hurdles. People broke down the fences surrounding the stadium to get in that day and it was completely packed with people standing on all the stairs, entryways, etc.
Atlanta 1996 was pretty cool. I could just be a fan then as I was just out of college. Michael Johnson WR race was awesome as was seeing Gebrselassie Tergat.
