April Desktop Wallpaper
One of my favorite sites that is not necessarily horse related, although there are certainly horses there, is The Pioneer Woman. Her blog covers food (awesome recipes!), photography, and just her general adventures of being a city girl now living on real cattle ranch. Her content is interesting and her sense of humor is refreshing.
Anyway, she takes great pictures, and sometimes they are of the horses on the ranch. She is offering this beautiful shot for free – I have it as my desktop wallpaper at the moment.
