Just found this thread and enjoyed reading some of your experiences and ideas. My DD and her partner sold their house and bought a motorhome and with my gorgeous Grandsons (5 and 7 when they left) took off on a year's tour of Europe and Morocco.
I tried to hold back the tears as they drove away in January, telling myself it's not really that far - and we had planned to go out and meet them in Spain in March or April. Deep down though I doubted that they'd ever come back and settle to life as it was here - and I think that's likely to prove true.
They are having amazing experiences, drove quickly through a very cold France, through Spain and found the sun in Morocco. It's easier and harder than I expected, the first few weeks I had constant a gnawing sensation in the pit of my stomache and felt anxious if we went a few days without a message or FB post. That couldn't, and hasn't, lasted and I have sort of got used to it and really look forward to messages, photos, the odd phone call and her blog.
We did met up with them in Spain and had the joy of seeing the Alhambra Palace with them at the end of March. We'll try and make it to wherever they are in September. As they have no permanent address sending anything isn't possible and of course they are very short of space. I also think that if they can possibly afford it they'll settle on a finca in Spain and that's where they'll stay. I know it's not the US or even further Australia but it's too far for them to be involved in family celebration etc, etc and I feel sad that they and my 2 younger grandchildren will never be as close as might have been. But as some of you have said, they are happy, living the kind of life they choose and I love them all dearly.
