A major problem is that the game managment agencies treat hogs as game instead of pests, so you have a limited season and lots of restrictions (no NVGs, lights, suppressors etc) and so on. Kind of hard to eliminate a pest when you have one hand tied behind your back because the idiots think its still a game animal. Same goes for deer down here, too. Huge overpopulation not enough killing.
They're not game animals in VA. In NC, they're only game animals in the western (mtn) part of the state IIRC. Ergo, it's open season year round. From what I recall, lights and such are legal in NC. I haven't checked into that for VA.
Dunno about other states, but the deer season is pretty long in VA. Gun season alone runs late Nov through early Jan on public lands (WMAs, more restrictive on National Forest lands). Private land hunters in Northern VA, where the population is the most troublesome, have a season that runs till mid March (does only).
BP and bow doesn't run any longer, but starts earlier. Bow hunting will let you hunt from Sept to March if you have access to private lands and can take advantage of the special NoVA regs.
