Input needed for efective hog managment.

I think we need to call national geographic.. But question i have a place that is bordered by 2K of deer lease that feed yr round, and wont allow me to hog hunt, i have a 1K acres next to it that feeds, i have hunted that place from end of january to end of april atleast every weekend and caught hogs everytime yet the land owner quit feeding once summertime gets here bout may and i cant seem to get a hog but when i do get on one it leaves to the nighbors place but once he start feeding for the deer and planting bout september it is on again they are everywhere??? Lots of pressure but it seems they left when the food source stop, yes i have ran it alot thinner over the years where we used to catch 4-8 every other hunt we now get 1-2 until the feeding stops then we are lucky for one.?
