I went to Everton Park earlier this week, I went back on Saturday to photograph the litter there and the surrounding area.
Most of my street photography is done in the city centre. Yes, the pavings are splattered with chewing gum, but there's little rubbish, at least compared to the suburbs, the city centre is sparkling. You don't have to venture too far out of town and rubbish is startling.
Ironically, in Everton Park there's an information board claiming it to have the "Greatest View In Liverpool".
I rarely photograph in the suburbs, mainly because you don't see many people about. But I think there's good reason to go off and explore and make some litter GIFs.
