South Liverpool was discussed in another thread some weeks ago.
My all time "hate to visit" was Farrar Road, the then home of Bangor City FC.
My first trip was a Thursday night fixture towards the end of the 1988/89 season. We got held up due to a bad accident on the A55 and arrived late.
Pulling up in the car park we spotted an old Triumph Dolomite car which had had all it's windows put through, and then filled to the brim (literally, to the brim....) with concrete....
The locals would all speak English until you happened to be standing near to them when they'd then start speaking in Welsh.
Also, the terraces were entirely surrounded by metal fences - a hark back to their European Cup Winners Cup exploits in the mid 1980's. It made the place look and feel like Stamford Bridge Chelsea, in the 1980's.....
We got beat 0-3, and, due to the late kick off, didn't get back to Morecambe until the very small hours.
