ZPBM, I reckon someone so aggressive at knowing what you are doing has an awful lot to hide themselves. It would appear that the exhibited bravado/craziness puts people off from taking note of what they are doing, kind of like a reverse psychology thing. Perhaps they are lawfully scaring everyone away and may well be a brilliant ploy to disguise a meth lab, hydro house etc etc. 1/2 an acre would be perfect to do this kind of thing. Assumed too pricey for the average cook/grower. Plenty of space between houses so plenty of privacy once he has scared you all away. Can't hear noises, smell stuff. Perhaps you do need to get those cameras going, give him a bit of a scare. hahahah
