Most of the pig hunting in Texas is done at night, unless you are using a helicopter to herd them. Pigs have no sweat glands so they are nocturnal for the most part in 90 deg+ days. Been there 4 times and all sightings were at night using thermal imaging. Lots of cattle mixed up in the fields so you have to be careful. The breeding season is all year. I doubt hogs breed in Alberta or Sask in winter but I could be wrong. Traps work if the population is high. Hope to go there again this spring. Last year March it was 90 deg F in west Texas making it pleasant to be outdoors at night, sleep during the day. No licence needed, no orange clothing, no restrictions on firearms and you get to use all those hi-tech night vision toys we can only dream about here.
