Directions
Mark
Best way to Wrexha, from Bristol.
M5 then M6, then take the M54 to Shrewsbury.
Look out for the signs for Oswestry, and I think Wrexham will be sign posted from there as well. If not it definently is when you reach Oswestry (think this spelling is right, but you'll know it when you see it).
You will then be able to pick the site directions from the map I sent you guy's.
Hope this is useful.
