I went out last weekend, when it was above freezing. Got a very long run. A big 'ol boar coon was cruising looking for love. That guy must have checked every den in the woods. After about 3 hours they treed, and had the grease. There were 2 in the tree and we could tell which was the male, and dropped him out. The Garmin collars told me the dogs had tracked that old boy 4 miles, although he never was more than a mile away from where they first struck the track.
