Well, thank you for all the entries.
I think that was probably much more difficult to find something for than most, apologies if so. I've been suffering from a bad back and haven't been out much in the last few weeks so didn't manage a single entry myself...
But some great pics, split generally into "Lonely bike" or "Lonely person/object seen from a bike". Very difficult on the latter to get the sense of being alone rather than accompanied by a bike, I think.
On the lonely bike front, I particularly enjoyed the black and white from
@yo vanilla
Lots of inventive entries on lonely objects, strawberries, mushrooms, hats, but the abandoned machinery (winch?) from
@Oldhippy was rather eyecatching (I had to crop it to get it to display for some odd reason, apologies):
But my two favourites were, on the lonely bike front, what I imagine to be an insomniac Specialized contemplating the dawn from
@newts :
and the tree, all alone despite being in a crowd from
@PeteXXX
So, the winner is [drum roll]
@PeteXXX for their lonely tree.
Over to you and thanks to everyone for the entries.
