Well, I'm assuming you want direct evidence, i.e., that the horizon itself appears to be curved...

I'm not sure if this qualifies in your book, but I've heard that this can be "seen" at the Bonneville Salt Flats in Utah, and this wikipedia article seems to explain that it's somewhat of an optical illusion:

The indirect evidence is that when looking out into the ocean, you see the top of a sailboat that is coming towards you from the open ocean before you see the rest of the boat itself. This would be impossible if the world was flat.

There may be some more useful info here:
