Long distance running

I think more times than not the dog gets to far behind and the scent gets weaker and when it runs across a warmer scent it takes that one leading one to believe that they've ran the same hog hours and hours, at the beginning of summer me and my partner hunted a 13k acre block of timber company pines with branch heads all through, me and Billy got away from the group and got our own hog jumped, several hours later the other groups dogs get on the same track as ours but several hours behind and whenever they would get down in the bottoms where they could smell good they would all blow up and them boys kept calling us and swearing they was running a monster, they had a walking bay and the hog was whipping their dogs and just walking off, mind you they had 15 head of piranhas down, when I got around to them finally, I showed them on my Garmin where their dogs had followed our's track step for step and every place they had a "walking bay" was in a creek bottom where the scent was lingering longer and it's more open and the dogs could really move better, the timber company won't burn around here so it's bad kinda thick, miraculously every time this big bad boar would get up in the pines and thickets they would go back to "running" him would "walk bay" again once in the branches, a lot of times these monsters and all day races are just a lack of knowledge and knowing the game and terrain, very rarely do we have all day races in the summer because we won't let the dogs runs that long, but in the winter or cooler months we will and around where I mainly hunt if a dog is lining straight out of an area then most times it's a good male, there are some hogs who refuse to bay and will literally run themselves to death, there will always be skeptics that say the physiology of hogs will not allow them to run great distances over a period of time, I caught a boar 3 summers ago that we jumped at daylight and by 11 am he had done covered over 18 miles according the Garmin and never left a 3 square mile are, the farming area I hunt has countless spring heads and branches good flowing creeks and farm ponds and unlimited food supply for the hogs, about 10 years ago I caught a huge sow one summer that refused to stay bayed, she would go from branch head to branch head and knew where every pond around was,only way I caught her was I ambushed her with a bull dog as she was coming out of a pond that had an artesian well coming out of the ground, this was mid summer and this huzzy knew the game and had survival on her mind...
