Saturday Photo Scavenger Hunt: Lines

Become a Photo Hunter View Blogroll

I've joined the Saturday Photo Scavenger Hunt...click the links above if you want to join too. I love the idea and today's theme is lines, in my case, these are lines on a curved surface. I visited a winery and this is a picture of a steel fermentation tank. Those bands wrapping around it carry cooling liquid to maintain the temperature of the fermenting must in the tank and it's all controlled by a computer.

Now you know :)
