There is a photo contest by @friendlymoose called POBphotocontest.
Every week on Sunday a new round starts and the motto is announced.
To participate, you have to publish a post according to the theme, then leave a comment and a link in the contestpost and use the tag #pobphotocontest.
There are POB tokens to be won, which will be distributed as rewards for the published post.
Also @good-karma has donated Ecency points for the winners.
So it's worth joining in there.
This week's theme is Yellow and here is my contribution.
I don't have that many yellow things to photograph. Actually, orange is my favourite colour and if it's going to be garish, it's going to be orange.
But we have a yellow garden hose.
