Not the most reliable of indicators I know, but the OS ticket sales now has no 'select ticket' buttons for the Arsenal game. Plenty of tickets for the Polish though, and a few for the evening match against Scum.
Could be that the site is just in error (again), or it could be waiting for some peon to come into work Monday morning to re-allocate. But if we have sold out so early - Sunday TV game as well - maybe it's an indication of our increasing supporter confidence, after all the doom and gloom about staggering to a sell-out for the Dippers' Monday night game?
