TEXAS Priority Post to BC

Hi,

Someone sent out a Priority Post small package/envelope from Arlington Texas to come here to me in the SE corner of BC.

Sent: Monday Nov 6.

Thursday Nov. 16th today, and it ain't here YET!

Is the package coming by dogsled, or what???

Anyone from Texas ever sent a priority post from Texas to Canada, especially BC, and how long did it take???

Thanks
