I must say I don't recoment this but , HEHEHE trebles woven into the lead line will make the unlucky ******* think twice next time. If they are being pulled by hydraulic or gas puller concrete dye in a small bag taped on the line will make it easy to see who's a thief. I know of a fellow who was loosing his generator to some ambitious thieves ( they had to hike in quite a ways ). He JB welded the long floor scraping razors to the handles and was rewarded with a large puddle.
