Holy crap! (literally I guess). I did some of my wedding portraits with my mare, but my mom watched she and I both like a hawk to make sure that I touched the horse as little as possible. If I didn't have a mom who raised me in the barn it wouldn't've been possible.
No way will my daughter take a chance on THE day (the 25th of this month!!), but there is going to be horse(s) involved (unless the weather is bad). She will do another photo shoot later though, with her mare.
