You need to notify them of each state you plan to travel to.So are you saying a request is good for 12 months and you can travel anywhere during said 12 month period?
I send in a 5320.20 for all states surrounding Georgia.
You have to supply a specific street address that you plan to visit... so it's a bit unclear what might happen if you were stopped/questioned in a different part of the state, not along a typical path of travel.
Not worth asking the ATF IMO. Don't want to rattle the cage too much.
