I didn't finish the challenge last year - I made it to "L" and my poor sweet Mr. Goo (Guinness) passed away. He had been with me for a very long time - almost 13 years - and was just finding it too hard to get around. His hips just gave out on him.
I miss him, but it broke my heart more to see him in pain and unable to move freely.
But anyways, if you're interested you can check out the A to Z Challenge at http://www.a-to-zchallenge.com/ - it's always a lot of fun, and you'll find some other great bloggers along the way. It's only mid February, and there are already 708 other blogs signed up!
