My first memories are really the 97-98 season (age 6-7)...
I remember being annoyed that Niinimaa was gone. But then like 3 weeks later loved Dan McGillis after maybe 2 games of seeing him.
My first vivid memories though were the Lindros 1999-00 (age 8-9) injury sagas and then him sitting 00-01. And hating Clarke because of it at the time, I vividly remember the infamous interview Clarke did, was sat watching our NHL highlights show and it was being discussed on there.
Then I really became a "proper, knows what is actually going on" fan in 2002-03 (age 11-12). Buying The Hockey News, checking NHL.com every day, knowing players around the league. Having a Michal Handzus calendar desktop background and Flyers screensaver on my parents PC.
I remember scribbling down the Flyers potential line-up on the back page of my school book the day after they traded for Amonte and being like "we are winning the ****ing cup". And getting frustrated that while there were hockey fans in my school all they cared about were Manchester Storm... while who I liked a lot and went to games I knew the level sucked vs NHL and was no-where near as special.
