I live in a sparse but seemingly good area and see no junkers in yards or just growing flowers around them. Our DMV is also pretty lax, one rig I finished I bought in 94 and it sat inside with no plates from when I bought it out of state, $100 max fee for not having it plated is the most they can charge. Just needed a vin inspection sheet.
Being a farm I paint a good many tractors, do alot of clutch, cylinder and sleeve R@R and its just normal life.
Alot do burn stuff here and the smoke cant be good for the air, I do and maybe better or not but ive an incinerator that puts out no smoke from the bad things I burn so maybe its cleaner.
