Psychoactive corrosive Ivy infestation.

Perennial maze had become the crop of choice, very little tillage was needed - in fact many fields went years with out any tillage.  This was great because of the low input cost associated with such a crop made wide profit margins, but problems were developing; the ivy was the worst, vine's grow better than most other plants in a high CO2 atmosphere, easily out performing the perennial maze, several species of ivy have formed a symbiotic relationship, enabling those plants to form a biological mega-structure, many of the symbiont that form that matrix have become extremely toxic borrowing certain traits from the poison ivy and poison oak that make up a substantial part of that web of hideous life, and incorporating them in their own genetic make up, and in do so have showed signs of extreme toxicity.  A new variant of morning glory excretes a psychoactive scent that utilizes the impulse control in the more complex organisms, this is perhaps the most unsettling of the ivy's; "the ivy" as it is called is resistant to all know forms of herbicide, robotic plow systems can be used but the plant material is highly corrosive usually disabling most machines.  Burning it was the most used method of eradication, but the smoke is noxious; the weather conditions to be just right, proper authorities alerted, and any down wind residents fifty mile's or less away - evacuated.

Predisposed to the fugue.

The still hot, pyramid five beltway ,warms his feet, pedestrian only - no private cars allowed, both sides of that narrow street is Zip car parking only, and at this time of morning most of them had been rented out and are about.  People stream across the belt drive and down the streets that run out from it, like rays of sun - not minding zip car drivers at their own peril, wandering out through the next three blocks, arriving at the shed or shop of their employment.  Some of these people would've liked to blunder out past the three blocks to the belt way park, and wander through the woods.  A small amount of those that went to the park would eventually go out to the fields to wander about as tramps,freebooters,or the more forgiving term "hikers".  Lucky's shed is farthest out on the ring and next to the wood, often he forgets about making the right turn into the shed, and goes into the park.  On those occasions he thought about going on a hike, a long hike - but eventually shakes it off, and turns around.  He's soon at his building, hook's right and goes in
