Warrior is correct. Never say Never. Just the other day. Had coyote. 10 ft of chain. Saber Tooth drag. Went 15 ft into cutover. Made circle. Came out went 300 yards down the road went in on opposite side. They ant spose to do that !!! LOL!!
Yes, I had a wolf caught on the edge of a road, go across the road, up the hill, get hung up and tear the place up, then get loose go back down the hill, hit the road, take it a couple hundred yards, down a hard pan clay road, then it rained AFTER, she went through there, went up across an open another couple hundred yards and finally hung up when she hit the timber. I was trapping just off the edges of fairly well traveled logging road and wanted them to get out of sight, but not that far out of sight! Next trap fifty feet down there was one two inch pine that was growing in about a thirty foot wide meadow just off the edge of the road. That wolf was wrapped around that little pine not more than five feet off the road in the wide open.
That is the only difficult tracking job I have had with my drags, but never say never is right. And if they head down a hard packed road it isn't going to hang up until they leave it. A gravel road a good grapple will leave furrows that you can track at 20 miles an hour... unless there is a bunch of traffic and the drag marks are all ran over. Pretty rare for them to head down a road when they get pinched though, they usually head for the nearest cover. The other issue here is that if it snows 8" after you catch the animal it can be a pain to track, especially a pack animal like wolves or possibly coyotes, because there will be more old snowed in tracks and trails than just those made by the critter with a trap on his foot.
