For me it's Llanelly Hill, near Abergavenny.

One of the best drainage systems ever due to the slope I must add, but the rest....
On a fine day anywhere else, it would be sleeting up there.
Gale force winds were more than welcomed by the 14 brave diehards.
Kick the ball out of touch and it would end up up 3 mile down the road in Clydach.

For bog conditions Crickhowell was a big winner.
