Agree. Just check the 'In Transit" since you're going on to AK. Do not mention(verbally) personal protection from the human kind...they just don't want to hear it. You need cable / trigger locks for both firearms and make sure you bring all your documentation with you should you be asked to enter the office. Once inside the office, they will not let you back into the coach to get any paperwork and will more than likely raise their level of interest and possibly give them an excuse to do a search...don't ask. As for other documentation(mainly, pets), it all depends on the agent as to what they may or may not ask for, but whenever guns are involved, they sometimes take a little harder look. It also depends on what's going on with the world as well...different levels of attention.
No other forms are needed - the 909, cable/trigger locks and with $25.00 CAD, you're good to go. Bob
