I can tell from the different degrees of rust that these bolts were changed at different times. The largest one looks pretty old Linda. I imagine he had a very hard time getting these off as rusty as they are.
O, hark, O, hear! how thin and clear,
And thinner, clearer, farther going!
O, sweet and far from cliff and scar
The horns of Elfland faintly blowing!
Blow, let us hear the purple glens replying,
Blow, bugle; answer, echoes, dying, dying, dying.
-Alfred Tennyson (1809-1892),
The Splendor Falls
Interesting subject. I'm not sure if I care for the red in the upper left and there's a glare in the extra space on the right, both could be mostly removed with a tighter crop. Not bad.
Linda, those are bolts, not screws! Hehehe... This image may elicit many different emotions from as many different people, but it reminded me that I need to fix -our- lawn mower, so to me it is a bummer. Bummer. Nice shot, though... :)
