My son and I are headed to AK from Colorado to hunt caribou. This will be his first big game hunt of any kind. He'll be equipped with a 7mm-08 but I would love to save carrying a second rifle and want to take my 500 S&W instead. At the same time, I want to take him up the Alcan Highway and was currious what hurdles and hassles I may need to deal with crossing the border. Any experiences or guidance would be appreciated.
