No idea what our stage is called, though its near Maesteg, starting up by the golf club (ish) and ending at margam park, going through the forestry and down and around what we call the "blue pool, or the blankie" which is a long disused manmade (but beautiful) reservior.
I usually went at the corner where the cars would take a right turning going downhill on the road down to and alongside the pool, then after a good while you would see it come back up on the otherside (there are 2 roads going down to the pool, they go down one and re-emerge up the other after a few mins). Always a load of action there and seen a few cars topple, aswell as a few cars that never came back up the other side!
Eventually they end up in Margam park, I can never forget years and years ago sneaking into there as a child (easy to do from the forest) and watching a Corolla that was just about to win, choke on the final straight. If I remember right (not sure I do) it cost him the championship.
They also host the Mintex Rally, went there one year with a friend, we didnt know anything about the rally, we just happened to be riding our mountain bikes (as we did every weekend) up the forest and saw that there was a rally on! Can't fault it.
It has been a while since i've been though, maybe 2-3 years, since I moved away, but I will be attending this year.
