Or even "to which countries have you been?"
Not to split hairs or owt.
From west to east (-ish) , I've been to:
USA, Canada, Iceland, Portugal, Spain, France, Ireland, Belgium, Netherlands, Sweden, Austria, Greece, Yugoslavia (Croatia and Slovenia), Russia, Turkey, Sri Lanka, Japan and New Zealand.
Intend to visit:
Chile, Cuba, China, and I've no doubt I'll end up in Australia at some point too.
