I think you've noticed the difference between ISO's. I can't imagine that anything above 100 would be necessary to shoot something in open sunlight, and the 200s you've posted are the ones where the reds are blown. I might also try underexposing by a stop.

So the scientific question is are reds more reflective? Or is it the surface that is reflective? Either way requiring me to underexpose.
Open sunlight. The two really blown ones were early morning. The middle okay one was late afternoon.
are you sure your metering was right...check out the histograms on both of the shots.
huh...? =)
Edit: I guess I don't know how to read a histogram. I've never looked at that screen. They're not on my camera anymore either. There's probably software I can download..
So what we're all coming up with is that they're all just overexposed? Inorder to get the centers bright enough though, I'm still going to have to overexpose and rely on Photoshop. Like this one I entered into Freestudy after toning down the reds in Hue/Sat:
When working on mostly red images you might want to edit with the Gamut warning on. If ya look at the top image you're blowing red completely out of gamut. The bottom is the red channel of the image - way over exposed.

I'm not sure how you can determine it's an exposure issue when the camera has already processed the image you are looking at a histogram of. You can oversaturate the channel and get a histogram which shows that channel as being blown out.
Again I would flat line (or take them negative) your camera's saturation setting and then take some test shots with what you feel is correct exposure. Then look at the histogram and see what it tells you.
On the D80 be sure to check your settings under "Optimise Image". You may be setting for Vivid or MoreVivid or your overall saturation may be set too high. You may want to check the Color Mode too, and make sure it is not set to IIIa, although this is recommended for photos which are not edited in software. Mine is always set to II which is AdobeRGB.
A general rule for the D80 seems to be to underexpose by -0.7 EV and this seems to keep the reds in check - but red does blow oh so easily :-)
