Here are some photos near the Exeter Quay. Maybe there could be a 3D model from this. I don't think I got far enough away from some angles, did not want to fall in the water. Please suggest links to other ones, maybe it needs a good zoom lens. Also the design may be too complicated. Something simpler could be worked out. It just needs a focus for a walk, real or imagined.
Forgot the link for Bristol as playable city in previous post. It is here . Aim for the year is to move the Colston Hall to Exeter Bus Station or at least a scale model.
