26 things

For the past couple of days I’ve been playing a photography scavenger hunt called 26 Things. The idea is to take one creative photo of each of 26 themes then make a web gallery and mail the URL to the organizers on August 1st.
So far, I’ve captured six themes: food, water, colour, little things, and time.
But there are some tricky ones. A creative depiction of love? Footwear? A sunset? I’m not even sure where to begin getting creative with a sunset.
Sometimes I’m not sure which theme to assign to a photo. Take this one, for instance. Is it authority, transport, construction, or signage?

Maybe it’s just badly spelled.
