ok need some advice here. saw something very odd when out looking for new ground today. went for a walk down a small privately owned path beside farm land. i saw a small trail heading off towards some light undergrowth. i stepped off the path and moved towards the undergrowth only to hear an extremely loud bang to the left of me, i turn around and see a large amount of smoke which appears to be coming from the otherside of the undergrowth to the left of me. i got out of there quick as you might think. anyone know what this might be? maybe just some diverstion tactic for an existing grow?
