I've been to a few away games this season and I would say that's a pretty good reflection of Notts away following on 'average'
Obviously the nearer the away fixture,the better the attendance's, Swindon came to Meadow Lane on a Tuesday night and so will Carlisle in a few weeks time so the away following will be reduced than if it was on a Saturday,going down to Exeter mid week was a bit too much of an ask for me
