It wasn't snarky.
The places you can park over there require a long walk down to Upperton Road.
It's long been said that footbridges near the railway bridge would make access to the stadium much easier, so you could access the stadium from the south end, but seems no one is interested in building them.
So I didn't mention these places, which I've used cos I'm relatively healthy and don't mind a walk, since you wanted somewhere closer for your dad.
Would Freeman's Common be too far?
