Haven't been to Dunfermline, ICT, Arbroath or Raith yet so can't really comment on them. But Arbroath sounds like it could be worth a trip. Maybe one day...
Might have gone for QP, I do actually quite enjoy the novelty of an almost empty Hampden stadium. But as a regular at Scotland games, it feels kind of like a home from home. So not sure it counts.
Partick? only has 3 stands, which is shit.
Dundee Utd is alright, I guess. But I stayed in Dundee for a while, & tbh I'm not really that keen on going back there.
Airdrie I actually quite enjoyed. Mainly due to the trip to the Time Capsule before it (which my kids loved) & a win, which always helps.
Despite the fact it always seems to be pishing down, mainly due to the proper old fashioned stadium, i have to grudgingly say Morton.
