sweet potato man

It's been a while since going to The Galleria korean market in Sunnyvale. I hoped to see this old man there who sells freshly broiled sweet potatoes. I had imagined how great the korean style sweet potato would be on this cold day. So when I saw him under a newly built wooden awning with his little machine/broiler, I was thrilled! He's a jolly man; so he enthusiastically agreed when I asked if I could take a picture of him. He threw in a few extra sweet potatoes at the end of our shoot.

I wonder....
