In what country are the girls most approachable/aggressive?

Obviously, the country where it is easiest to meet girls is the one you happen to be in at the moment.

But (for those who have been around the world a bit) where do you find that women are more likely to either show clear interest or actually make the first move? I'm not talking about where they are most attractive.

I found while traveling in Europe that it was much easier than in the US, but that may be because I was staying in hostels and places like that, and also because traveling puts you out there to actually meet people rather than being stuck in a routine, as well as giving you a better mindset.
