I don't normally try to acquire USPS commemorative cancels but I saw a few I thought I would "try" in the last USPS bulletin. This Trout Creek MT cancel was one of them. Trout Creek is a small town of 300 in Western Montana. It's known as the Huckleberry Capital of Montana and every year they hold a Festival to commemorate that fact. This year was the 31st and was held on August 13th, as commemorated by the cancel on this envelope. I like this one because it's similar to the the circular commemorative cancels CanadaPost uses.
