Suspicious Structure

First attracted by a strong unpleasant odor, I gazed through the dense overgrowth to see what appeared to be toxic fumes spewing from a small smoke stack atop what at first appeared to be an abandoned structure. Whatever was being made (destroyed?) inside was covering the sky and immediate area with poisonous exhaust, I took my photograph and quickly retreated. The addition of hand coloring helps express my emotional reaction to the discovery of the suspicious structure that day.
