Each Metro Cup/JBC team I've supported over my years of following League always seems to drop out of the competition! I originally followed Ryde-Eastwood Hawks (they had a number of ex-Eels in the side including the L'Estrange brothers, Colum Halpenny and [I think] Ray Mercy) and went to a number of their games including one incredibly cold night at Henson Park versus Bondi Roosters (the Easts feeder team at the time). I also supported Kellyville Bushrangers probably because they were the Eels feeder team. I've been to two Metro Cup grand finals (when they were stand-alone games) including the Kellyville v Wenty grand final in 1998 at Parramatta Stadium (with a crowd of 6,000) which was a brilliant match with Trevor Schodel (and, I think, the Capovilla brothers - or were they playing for the Bushrangers?) winning the match for Wenty.
Obviously, Kellyville abandoned Senior League (they are a Junior club only now?) and Ryde-Eastwood is no more at this level.
Living in the Eastern Suburbs now I'm hoping to see Newtown at Henson Park a few times (PL and JBC) in 2006.
