Only went in the east stand seats once, can't remember why. I went in every other part of the ground though.
Quite a few changes to the east end post 1966. The NE corner was reduced in size quite a bit, a large chunk taken off the back as was dangerous and that reduced the east end capacity a bit. Then in the away corner quite a large portion was fenced off as the back of the stand went too close to the east end roof so rubbish sight lines and dangerous. There was a standing paddock for a while at the front of the east stand, they built a wall across and tried to make it two tiered, this was probably mid 70's to mid 80's. I think this was gone by around 88 and for a while they just had lots of empty steps at the front with no seats or standing posts, this again reduced capacity. Early 90's I think they put seats back in right to the front.
My old man always said east end is where kids and those who just turned up for the big games stood. And was always favoured by away fans pre segregation, this us like pre 1960..
