I'm going, I was very surprised to get tickets for our last ever match (probably) at Highbury, given that I never have got them before. The people at the box office said it was undersubscibed, so tickets should go on general sale.
I was going to go by coach but given the ridiculous starting time (4 am I think), I'm going by plane instead (cheaper than the train, even with BA), staying over one night. Should be good except the match itself, which could well turn into a nightmare. But you never know.....
