Can you name the cities with a population greater than 100 thousand, which lie within 500 kilometres of Vancouver?
Populations are by urban area, according to citypopulation.de, suburbs, such as the many in Metro Vancouver, are discounted, although distances are measured from Vancouver Proper
Probably going to do some European cities, mainly. I'll try and focus on interestingly placed cities like Basel, Switzerland, which sits on the France, Switzerland, Germany border, or perhaps Gibraltar.
