Maybe my case was extreme where I wanted to take a gun into canada but I lied to the border agent about being arrested for a dui and they still did a check and denied me. From my expierence they can check anybody they want for any reason. They told me a person just traveling through has a chance to not get check but if you are hunting or taking vehicles and such things across the checks become much more frequent. I thought about just taking the bus up there and my buddies could be waiting on the other side for me I think it would work I can't imagine them being able to check everybody in a bus right????
Anyway it can't hurt to try if your going with the attitude that you are more than likely coming home and if you do I'm not sure which way you would go but I went through sweetgrass on I-15 the nearest bus station is greatfalls montana about a hour and a half drive back and the bus ticket is around $120 to brigham city utah
GOOD LUCK let us know what happens
