17500 according to other info http://www.barnsleyfc.org.uk/BBS/forums/thread-view.asp?tid=33054&mid=200769#M200769
Not saying you werent its just we have 2 siginifcantly different numbers and at least one of them is wrong. to be honest 12000 is less than I would expect it the "9000 to 10000" figure at end of Thursday is right - bit surprised if its as high 17500 as well but info from city tyke is usually reliable.
