In reply to richardh:
.. and in response to Simon "there is no bend" Lee!
Looked at it both ways last night, as you pass the Tennants, you can't see the queue of parked cars round the bend, on the admitted straight ( Yes, Simon), and you're accelerating because there's an open stretch coming. All of a sudden, if people are parked too far back, you could be into the back of a queue of parked cars if something was / often is coming the other way.
Whether this is a bigger issue than the guy who stopped on Sunday in the middle of the road under the North Butress, ambled to his boot to get his camera out, took a couple of pictures, and then eventually bimbled off, I don't know.
