The night ones are the best because you can see the shadows.
I did these two and some other ones on September 19, 2007 at 8 pm but I don't have all the pictures because they are on another camera. These turned out great because the light form the street lights made the sign glow.
These next 5 images were taken at 5 pm on September 20, 2007. That sun never came out that day, but one time and I was not at the site.
The first six images were taken at 9 am on September 20, 2007. It was very cloudy that day.
