Firstly lets stop using the word 'Fans' in this discussion. Idiots are quite simply 'Idiots', regardless of what shirt they wear....and they do wear every different club shirt.
At the end of the game there was some trouble down the right hand side of the ground (Left side from the Leeds end, right side from the Cas end), at the interface between the two teams tickets allocations. Quite honestly, I was too far away to hear any vocal exchanges however, it was obviously going on as I could see people in Cas shirts and Leeds shirts seemingly ranting at each other. The Stewards were quick to attend and draw a separation of these people in this area. I could also see a guy with a Rhino's flag waving it about as much as he could and stood in an area where there were many with Cas shirts and part of the Cas allocation...this was perhaps a bit provocative, and not the brightest thing to do!
It was also disappointing to see two people climb onto the pitch from the Cas end, one in a Tiget suit and the other without a top on showing his 'moobs' and have to be escorted from the pitch by stewards.
So call it half a dozen or maybe even a dozen idiots from within a generally good yet emotionally charged crowd of 13,100! Hence the vast, and overwhelming majority of RL fans in attendance can be proud of the support given to their teams on a cracking day for RL.
The 'idiots' in both shirts colours, tiger suit and 'moobs man' wouldn't be missed if they never attended another RL game.
