Thanks all. You know I hadn't even thought about it, and that is the most simple solution. I told my friend initially I could send her somewhere else until the stalls were built, and she said that was unnecessary. So she doesn't want me to move her, but I honestly don't want her horses (or mine!) getting scuffed or injured.
Let me give a bit of background: My friend Missy is close to 60 and has cancer. She cannot get out to be with her horses and take care of them like she wants. I've been friends with her since August of '10. I help her take care of her horses and in return she lets me keep my horse at her place for free. I'll voluntarily buy a round bale and a few bags of feed when I can sneak it in (she feels like I shouldn't have to do that). She is a very proud woman and extremely kind and giving, but she can also be rash and make impulsive decisions sometimes.
Me moving Savanna would be a good solution, but I would not be able to help Missy take care of her horses and work with Savanna like I need to simultaneously, since I am without a car at the moment. Even once I got my car, gas is so ridiculously high that it would just be unrealistic to visit both places regularly. Perhaps that is why I didn't automatically think of moving her to begin with. Maybe if I had given you the proper background information you would have seen that it would be difficult for me to do that. I appreciate it though, and understand completely how that would be a good solution!
