At home games theres not a chance I could get in - The majority of the stewards know me and know I'm banned.. Away games would depend if there are any Swindon police there, which you wouldn't know until you got there, not worth the risk.
I went to watch the Town at Brighton a few years back.
The Swindon copper who use to harrass me years ago (admitedly for good reason) was there and insisted on seeing my ticket. When I showed him he said he wouldn't let me have it back unless I told him where I was living now. I said I wasn't willing to, as I'd put all that behind me. So he kept the ticket and I went back to the train and home.
So.........the point of the story is, they do send people to away games, and they have long memories, and can recognise you when you have aged considerably. So I wouldn't bother
