With the size that these snakes can grow to be I'm not sure I'd want to grab a live snake, stuff it into a bag and haul it back to the ranger station for disposal.
I'm right there with you. A buddy of mine had an 11 foot long pet Burmese years ago, and it took four grown men to pull it off of his 120 lb rottweiler when it got out of its terrarium (one of those men was me, and, as some of you may know, I am a pretty big guy). The dog had some broken ribs, but he made it, and it took everything we had to get that snake put back away. I would not want to tackle one of those bad boys alone.
He got rid of the snake the next day.
