I find if you go up the Polmadie Road, just north of the M74 there's loads of street parking, an easy getaway right onto the Mway after the game.
I still don't believe all the guff about them taking you through the courts for parking at Asda mind. If it ever gets that far, and it won't, just tell the Sheriff that £80 or whatever it is, is unreasonable for 3 hours parking and offer them a tenner. It's not a fine after all, it's a "parking charge".Offer nothing and speak to no one. The threat of an increasing fine goes up and up but the amount to claim in court is actually not that big. If you don't want nasty letters park somewhere else.
If every fan parks in Asda then no one can buy any shopping. That's why the (threat) is there.
