Kicks, I used it maybe twice since it opened D:
Even in the older games when you could only donate one item at a time and it didn't warn you if you'd already donated the item I loved the museum (Even if it was rather frustrating!)
In Wild world, it was the lost and found.
In New leaf, I find myself hardly ever going into the police station now that I've built it. ^_^; I guess some things never change!
Kicks. I check their daily since I got it pretty recently, but I still don't really see the point unless there's a certain pair of shoes you're looking for.
in city folk I didn't use the auction house at all.
in new leaf, it's the roost believe it or not. never went back after getting all my job rewards (and I got them a longgg time ago) ;;
i also never visit katrina and kicks only gets love because I need a few more shoes to complete my catalog.
