Retired Teacher who loves to travel

I am a highly responsible former teacher (20 years in a technology center). I have had cats and dogs for pets most of my life and can be a loving sitter for your family pets. The only thing I don't feel comfortable with is walking very large dogs, unless they are totally docile. I am not at all frail, but neither am I super strong and fast! I enjoy yard work and can carefully follow any instructions you provide to take care of plants--indoors and out. I am doing this because, not only does it provide me an inexpensive place to stay, it allows me to immerse myself in the community or countryside--my favorite kind of travel. I prefer a stay of at least 3 nights, but will consider any.
