Luckily, we have not had any attached ticks yet, and no deer ticks spotted. This area of the country, along with New England, claim the most cases of Lyme's disease. And now it's not just Lyme's but a few other diseases to worry about, too. We need a natural predator to wipe out the ticks, I'm not aware of any purpose they serve except to annoy people.
If you make it through the poison ivy and the ticks, you will find your self out back in the itchweed. At least the itchweed reaction is temporary and non-life threatening! Really, it's not all that hazardous here, because every now and then a tornado comes through and that takes care of the ticks, poison ivy and itchweed!
