Yellowblackmask,
I've noticed the exact same thing. I have been successful in catching the runners by getting in front of him and turning fresh plotts loose when he crosses...of course when I guess wrong on his path, I get behind the race....all part of the fun to me. Sometimes leapfrogging the fresh dogs is the only way...eventually, eventually he will stop.
We have done a few of the dropping fresh dogs last year. It either worked great or we would be on a nine to ten hour run. Just plain ole to dang long to stay on a runner. Also throws us into daylight timeframes which makes me nervous. To many idiots over here to chance running one into daybreak.
hog hunting can be fun sometimes...
Or turn into your second job. Haha. I am thinking of lacing my dogs teeth with venom from the poison dart frogs to attempt slowing these hogs down.......or guess they could just keep a mouthful and spit em at the hogs one at a time. Lol
