Jay, I thought there may have been an issue with security at the Olympic Park site.
I had a thought of using the shopping centre carpark at Rhodes. There is two hour free parking, plenty of light and only across the road from the current location. Could even be warmer on a winter's night!
At any rate, was just looking for a way to eliminate standing in the dark.
Myself, I will get down there next month as I am away as of tomorrow morning.
Cheers
