Right - after some thinking and discussion I reckon the easiest thing to do would be go to sheffield for comicon for people who are up for it. Then come back to barnsley to get changed/dump stuff.
Then out in barnsley for food/drinks and either stay out in barnsley (Scott Weldon assures me we can find somewhere with good music to dance to) or if all else fails and it's crap - head into sheffield.
comicon details here
http://filmandcomicconsheffield.com/ - tickets are £9 if you pre-book them for 11am entry - could meet up for breakfast in sheffield first if people are about - probably aiming to be back in barnsley around 6ish - any of you locals suggest a good place to eat in town?
I will probably get the train/tram there so I can have a drink if there's anything there
