We have plenty of wild hogs here in NE Texas too, though I haven't heard of them chasing any cyclists. The local weekly paper reported sightings of herds of over 30 of them just SW of another small town ~6 miles away- that town happens to be to our NE!
A couple of months ago, I saw 3 run across the edge of our front yard one night. Since then I've kept a 12 ga with slugs close by at home. There's been no call for it yet.
They've torn up several yards in our neighborhood- including ours. Found lots of fresh hog "pellets" in the front yard for several weeks in June & July.
And this business about "wild hogs prefer to run away", or "they only attack in defense or if provoked"- Don't count on that! At all. Not even a little bit. This means you. They can't read what they're supposed to do, and a lot of 'em wouldn't follow the instructions even if they could read. The fact is that while a certain percentage may folow those guidelines, no one can predict what an individual hog may do at any time. Avoid if possible, and ride a fast bike.

No foolin', you could get *badly* hurt. They're bad about ripping open the inside of a standing persons thighs if they get the chance- can you say "femoral artery"?
