I would love to do that. I've talked about it for decades, Pura would love it as well. Have a nice plot of land somewhere and just be nice to all the dogs who make their way there. I like dogs more than people and I'm not ashamed to say it.
Only problem is we can't sit still long enough to stay interested in land. That's the problem, "where?" We've been quite a few places and still haven't found somewhere we want to stay. So we just keep praying.
Oh well but they already have a plan for old age and what better than that? While they enjoy getting from here to there, helping out here and there. There are so many ways to help, with money, with time, as a host place as you did and so many places, shelters and foundations to help, as volunteers. and when you settle down in the perfect time you will do that, and it will be a wonderful life.
I will be praying for you and your plans.
