Jim, I've played Teignmouth (pronounced tin'muth if I recall correctly?) and its certainly worth playing if you are in the area.
The road crossing in the middle of the back nine isnt a busy road, but I drove across it one day in thick fog without realising I'd crossed a golf course in the car (this was pre H&S days so there was probably some slightly mad members out there!)
The last few holes seem a bit crowded and I think there have been some changes that arent MacKenzie in there. The plans and aerials show the 17th tee as to the right of the 16th green, but they are now well left. I think they also sometimes close the 16th as its a tiny green and use an extra hole between 17 and 18?
Cheers,
James
