WILD WEDNESDAY

I took a minute to scan some of today's Blips and noticed it was Wild Wednesday....otherwise I would not have known. I'm clueless about "challenges" that are issued and notice them only when a Blipper makes reference to one. Today's Wild Wednesday challenge, as I understand it, has to do with earth and wind.

The wind in this pic is caused by a racing Mazda who went a bit wide in a turn and hit the kitty litter. I'm pretty sure you can see the earth...in this case, stones that were, in the past, compacted soil (earth) before it turned rock hard. I know it's a stretch but it's the best I could do on short notice.

Will someone please educate me about these "challenges?"
