I was going to leave this until after tomorrow, wasn't I. However the mojo kicked in and I found time to do a bit of ground work on the TGR, which has been neglected for a few weeks.
So, with polystyrene, crumpled newspaper, and a few rolls of Modroc, we now have the rudiments of the gorge. Everything was given a rough base coat of a mix of emulsion paint, acrylic colour, PVA and some finishing plaster just to bind it all together.
Cilgerran castle will be on the rise as you leave Cilgerran station - the middle board being one of the quarries between Cilgerran and Cardigan.
At the front of the middle board will be a shallow bit of the Teifi.
This is looking from St Dogmaels towards Cilgerran. Castle will be on the right, bit of estuary on the left, then there will be a small hill to separate St Dogs.

This shot looking from the opposite direction:

And arrives (eventually) at St Dogmaels
