Where are you located? I don't know of a Wilson County in Indiana and google did not locate one. If close, and timing works, I might be able to help with the livestock.
It sounds like a great weekend if you position it that way. I would also make sure that *you* take care of the house sitting and livestock sitting *before* you give her the gift. Have it all taken care of beforehand so there is no stress on her part at all.
I hope you guys have a great time!
