daber! I can't believe anyone is as AR as I am. Yes, I too keep my traders in PinPics Number order. I find it makes it much easier to keep my list up to date. After every meet I can come home and uncheck the pins I traded.
As far as my keepers go, I have my theme books. One bag is for Holidays and Special Events. One bag is for International. One bag is for Patriotic. One bag is for WDW park pins (this is getting full so I may be getting another bag for park pins and then they will be separated into Park pins vs Resort pins.) Within the park pins, each park has it's own pages and then within the park I try to group the pins according to location, i.e. all Tomorrowland pins are together, all Fantasyland pins are together, etc.
Then, the bags go into suitcases and I try to remember which bag is in which suitcase. It never fails, the one I'm looking for is in the last suitcase I open.
Aren't you sorry you asked?

BTW, Mario's book is exactly as he described it.
