I was in the Vectra planning a route for a S.Wales run Lucky I didnt take the Z, I used a full tank of petrol & some of the roads I found really weren't Z friendly
I was on the hidden road a bit after you & I saw 1 other car over the 15ish miles the road spans for, The whole point of me going saturday was just to find that road because I couldn't remember where it was, you just have to watch out for the army
I think I spotted you about 5.30ish heading out of brecon.
