I'm not sure the Junction was around when I last visited although it'd be my first destination now - my main knowledge to Castleford pubs is the town centre, and primarily the route from the station to the rugby league ground.
Sports venues always seem to me a perfect launching pad for real ale, a high throughput - so why is it they always end up serving the same rubbish. There's one, I think Harlequins, who have regular real ale festivals 3 or 4 hours before kick-offs. With a ready made venue and the opportunity to kill two birds with one stone, it's a great idea. More places should do it.
