Why not open mouthed?

Pecos, So you are a Texan! I live in Cass county about 35 miles NE of Longview. We have a bunch of runners up here, but most of them eventually bay. Most of our hogs don't seem to leave the country regardless of what type of dogs you run on them. Most seem to run around in the same area (at least thats what the dog tracks on the Garmin would indicate). Sometimes up to 7 miles in a 1 sq. mile area. We have had big boars seemingly intentionally run the dogs through groups of hogs for their own self preservation. We've had big boars watch quietly as we were hobbling other hogs. Jumped them laid up in thickets and button willows until you nearly stepped on them on the way to a near-by bay. We have had times we've had hogs that simply stayed too far out in front that we didn't catch up with. We have not had a time that I can say we ran them out of the country with open or closed dogs. The last couple hogs we caught bayed up within a mile of where we turned out. One hunt was a couple hours long and one was about 30 min (would have been about 15 min, but had to drive out of the way to get to where the dogs were). Some of our hunts last 5 minutes, some 4 hours. I think regardless of the type of dogs folks run they have all had these short/long hunts.
