    HI Kebun! I love your blog and very interesting stories and photos from the other side of the globe. 🙂 It is so beautiful there. I noticed you were able to use my fetal development chart – I am honored! It was a long process collecting the proper data to compile the correct time frame. I will add you to my blogroll in my blog as well and come back to read more glorious stories from your beautiful farm. I’m glad you told your mother you wanted to be a farmer- you look like you are enjoying it very much. I will bet she is smiling .
