Had an hour and a half to think about this stuck at the border.
First is ur going up to Canada via peach arch stay left. There r more lanes open on that side.
When u come back the wait times are very optimistic. The sign says 40 minutes but we’ve been waiting an hour and a half. If u to peach arch stay left as lanes open there. But at pacific crossing stay left as lanes open to the right.
So if u see a line head to Lyndon or sumas. Go east young man!
