I live in the Pacific Northwest and occasionally we'll go to the beach to look for garter snakes. There's a colony of Wandering Garter Snakes and we love to search for them in the rocks on the beach. One day I saw one of these garters that was red-orange, as opposed to olive green. Same pattern as the wanderings, just red. Is this a flame variant of this subspecies? Are "flames" a common color variant?
