You're welcome! Sounds like your neighbor is a gem, and a good situation for your horse! Neat story about having fun with the little colt playing with your jacket!
I'm unsure if you are going live on the 7 acres across from your neighbor, or will be living 2 1/2 hrs north of your neighbor? Anyway.....
To answer your question - I have one horse, and she's a 20 yr. Old registered QH (people are surprised to hear she's 20, as she doesn't look it!). I mentioned in a previous post that the only reason why I have her here at home as a single horse is because I have the time to spend with her/care/feed/ride/etc. as I have a small business out of my home. Even then, I really, carefully weighed the pros and cons, talked to some seasoned horse owners, and after taking all into consideration it was the perfect situation for us. She is a seasoned mare, and noted for being well adapted to boot. Those things considered was the only reason I have her by herself. I can be with her all the time, (practically - one does have to run errands, keep appts., etc. even in the wilderness!) But it's proven to be wonderful for us!!! I love it, and she's happy and healthy, and that's what matters most!
Hope all goes well with your plans, and by the way, Crystal Falls, MI is one of the most lovely spots on the planet! :)
