Capacity is 26,300 - that is when there isn't an inch of grass available and there is not one seat left unfilled. Anyhting over and you've got people standing on the paths behind the hill....which due to comfort reasons will start to happen when the 26,000 mark is reached.
Atmosphere has certainly died down at EAS/Marathon over the years...i remember at the 44-0 thrashing of the Broncos in 2001 the crowd was electric....absolutely going off - "NEW-CAS-TLE---NEW-CAS-TLE---NEW-CAS-TLE". I knew we were destined for the Grand Final after been there that night.
Best i've heard in the past 5 years would be vs the Dogs in round 3 last year, 46-22. During the second half the Entire eastern stand was erupting the "NEW-CAS-TLE" chant out at very loud levels every 5 minutes. I remember the people, a good 300, out the back of the stand queing for food and beer were joining in to and because it is a big open concrete area out the back it was a very loud echo.
Good times.
