Back several months ago when I got my acceptance for a Nexus interview I scheduled the interview with a planned trip to Alberta. It was partially to cut down on trips, but mostly because that was pretty close to the earliest any airport could see me.
I could have gone to one of the land crossings very quickly and had the interview and dropped in for the iris picture on my next trip to an airport, but it also worked out that this is my first trip to Canada since my acceptance. I thought about canceling many times to just take a hop up to Detroit, but now my time is here.
Hopefully I will finally use the Canadian money I have been carrying around for months.
