Hey guys..
don't be afraid of carrying your pins on. Everyone I talked to in both the Newport News airport and the Orlando airport said it was fine to do so.
Just be sure your pins are organzied and together in the book (not thrown all over your bag), tell them when you send the bag through the xray that there will be metal showing up on the xray and what it is - offer to let them look through the bag personally.
When you think about it, although the backs of the pins are sharp, they are no different than ladies pierced earrings or brooches. (Brooches actually are worse than pins) and jewelry like this is allowed in carryon.
I would seriously hesitate checking my pins. In the future they will be able to search bags that are being checked away from your presense, locked or unlocked. Not to mention the insurance on each bag would probably not cover the cost of pins in a large pin bag.
One word of warning for you guys though... when you go through Orlando security do NOT wear the same shoes that you have been dragging yourself through WDW with for days on end. They WILL ask you to take them off and put them on a table and after all those days in the heat.. WHOOOAAAA
If you are still worried about taking your pins on the plane, get to the airport a little earlier, go up to one of the people at the security check point and ask them about the pins and see what they say about carrying them on.
