The Galapagos Islands
Africa to see all the animals
Sweden - just because it's where some of my great-grandparents came from, and I have already been to England and Scotland, and Quebec
Paris to see the Louvre (more ancestors)
Egypt
Petra in Jordan
Angkor Wat
New Zealand
and there are more, of course, including anywhere I could meet more Pet Talk people, but I'll stop there for now!
