I go through the US Customs at Baudette quite a bit in the Spring/Summer/Fall. I have forgotten my pass card a couple times. I stopped in the US side, told them I din't have it with me, they said no problem, you'll just need to fill out a quick form upon re-entry. I think I was in and out in under 10 minutes. Bringin your birth certificate would help. It not the Canadians who want your pass card, it's the US, so be sure to check in at Pembina before you head north, eh.
