Some interesting grounds visited this year.

Leamington stands out as being in the middle of nowhere. The Sat nav told me I was there a mile before I arrived and there was no stopping on the nearby roads, so the only option was the car park which was not obvious to find in the dark.
Barnoldswick is a tiny town in East Lancs and access was via very narrow winding roads, which were scary when a vehicle came the other way. The ground was around 400m off the main road down two unlit dirt roads and the car park was full, so that created a scary walk. The ground was actually decent with a lovely stone built covered terrace.
TNS - the dominant club in the Welsh Premier league for years are actually in England. About a mile outside Oswestry again in a very rural setting. They have two fantastic stands and the rest is just a concrete path and despite their success, they are the worst supported club in the league.
