Fridays seemed to have a better atmosphere in the ground. They were also much more convenient for me - they freed up your weekend and were a good way to kick it off.
This season is the first time since I was 14 that I haven't gotten a season ticket. This is due to me, and the people I go with, having pre-existing commitments on weekends meaning that it was not worthwhile in purchasing a season ticket. Instead I have been going to the games that haven't conflicted with my/my friend's schedule or to any away games that haven't been on a Sunday.
I never really understood all the complaints about Friday nights. I live abour 30-35 minutes from Hull. I've been at college and not getting home until around 5pm-ish or just after, and I could make then no problem.
It won't affect me for next season as I'm starting Uni this year and will be living away, so I'll only be able to attend the games towards the back end of the season (and our playoff push

) and I'll be subscribing to FC-Live instead. However, if I had have still been living around here then I would have preferred Fridays (and wouldn't have gotten a Season Ticket if it was Sundays).
