In White I generally spend all my time in Route 3, breeding. You see, ever since the start of April, I decided I wanted a special Herdier, I am still aiming, breeding, for that one...
In Black though, I'm training my team to level 100 so I can finally reset the game. As a result, I'm always stuck in Nimbasa, lately though, I've been exploring the rest of Unova to find Pokemon to breed and due to that I feel like I'm going to be stuck in Route 3, breeding again. So literally in Black/White I'm always breeding in route 3. XD
Seems like Nimbasa is popular though :x
