Beaver Creek/Alcan border crossing & other questions

We crossed the border from Alaska to Canada yesterday and from Canada into Alaska today going to Haines. In both these two crossings and our two crossings a month ago, we were not asked about food, pet papers, or even alcohol. Each asked for our passports and I volunteered I had a couple long guns and they asked to see my papers on them, and that was it. Easiest crossings we've ever had.
