Great thread FP - I'll miss the old place, and can't imagine a ground where I'll enjoy watching the footy from quite so much (but then, that could be because we fluked great seats in 1986 and stuck with them).
I agree with your first two great memories, and a few Gronk mentioned - here's my top five:
1. First Game 1986 v St George, a great spectacle after four years at Belmore. Fantastic atmosphere, won all three grades (I think), and a huge 36-6 win in firsta grade. A great start to a premiership winning season.
2. Comeback win 1987 v Canberra - down 22-0 at half time, a schol mate of mine went home. We came back to win I think 30-22 which was a great buzz, and stirring my mate at school on Monday was the icing on the cake.
3. Buying food throughout season 1990 - for purely personal and off-field reasons... if you care to know why there's a short story (Forum Sevens) about it stored here:

4. Tour Game 1992 v Great Britain - national teams don't tour like they used to, and rugby league is poorer for it. Back then the seasons were at different times of the year, meaning GB could spend a few months during our season playing tests against PNG, NZ and us along with warm up games against clubs. We got a great crowd to their match on a Friday night, and our bunch of 1992 no-names gave it to the touring side earning a 22-16 win.
5. Revenge game 2010 v Storm - small crowd due to weather, but great atmosphere and a great win. Bought a wooden spoon along to the ground and waved it at the Storm at every opportunity as we tore the cheats a new one.
