Yes, really noticed the difference when we moved east about 12 years ago. And, as Sheena will testify, it ALWAYS rains in Glasgow. It was raining at Mika gig in May but I abandoned my brolly outside Barrowlands.
I think, tbh, I'll just bring my puffy black jacket and just put it on the ground in front of me. I would HATE to be freezing - would rather put up with the inconvenience of having my jacket inside, than suffer hours of queuing in the cold outside.
