Dad n I have brought a couple back from US. The last being in 2012. We were our own broker, 72 hours notice at the proper border crossing. Never any hassle from the US side, BUT we had our paperwork in order. Part of that paperwork was my US Entry Waiver that was required for me and cost me huge $$. Yep I was an a$$hole when younger, and still can be!
Also the Entry Waiver is temporary and has to be renewed unfortunately. So BOTH sides can be a$$holes. A Pardon is a very small step for gaining access into our neighbouring countries.
As I said I'm near a border and can try to help if need be, BUT I cant cross.
Good luck
