Hi Folks, here I am in the US where many of us are gobsmacked and embarrassed. The theme will be "Eve of Destruction". Haha - just kidding. For a theme I going to use "Animal, Vegetable, or Mineral". It shouldn't be hard to take or find pictures, especially if you play with the definitions. Here are mine to get you started. You can do three of one or one each of three, or mix and match, whatever suits your fancy.
Animal: a snowy egret in flight.
Vegetable: I am not sure what sort of flower this is, but it caught my attention. It may be of the lily family.
Mineral: Ice coating my front door light.
Have fun! I'll be around tomorrow to see your pictures! Oh, and many thanks for using my farmers' market "Shops" photo as banner shot. Puts a smile on my face.
