I agree, but I'd like it better if the horizon looked straighter (and the trees more upright - or were they really leaning?). Rotated 3 degrees left in PSE:

Actually I believe you have it tilted, on a wider version that I have decided to use the photo looks level when I place the grid over it.

Maybe so - the tree on the left in the wider view looks straight - so why are the others leaning? Pushed by one of the hurricanes? I was assuming those were Bald Cypress, which I had never seen leaning because they are so heavily buttressed by their roots - maybe they are something else?

Hadn't looked very hard but after checking I'll have to go with Penolta's remark that the image isn't completely straight.

Not to start with what I think I'll just explain how I normally check this with a reflection and when I'm not sure.

Just search a spot in the topcenter of the image and the same spot in the reflection.
In photoshop I connect those with the 'ruler tool' and then straighten the image.
Here I get an ofsett around 2 -3 degrees.

These are Cypress trees. I tried an offset of 3 degrees and it did not look good to me. An offset of 1 degree looked good. I am not an expert on trhis, would the shadow line up straight if the sun is not in line between the camera and the trees. The sun was no where near aligned with the photo although the light was very diffuse, with the cloud cover.

Ed, Ronnny is talking about reflections, not shadows. Reflections are determined by the position of the observer, not the sun as shadows are. They will always be in a line between the observer and the subject, as they are formed by the same light reflecting off the subject towards the observer, but bounding off the water's surface (never tried to explain this type of reflection before - hope this makes sense).
