Damn!
I tried to cheat by looking at the file name - no clues there.
It's definitely UK and it is on the mainland.
Go on... give us some more help... is it east or west coast?
OK. First clue, because no one has got it yet.
It's definitely sunset and its taken just 3 days ago.
Feel free to have another go.
It's definitely UK and it is on the mainland.
Hmm... the tent is yellow... custard is yellow... custard is made by Birds... birds live in an aviary... Paignton zoo has an aviary... the zoo is on the coast... ergo it's South Devon!
There is at least one other major clue in the picture.
