I've made a 8 trips in last 4 years back and forth over the border (RT 91, Vermont) with my sleds and no problems. Last year when I was coming back into USA, the agent wanted to know if I declared my sleds in the USA before I left and crossed into Canada. He said there is a form I should have filled out. Anybody no what this form is? Can I get it online? Can I file it online? Thanks
