This evening I checked the company website and no mention anywhere of vehicle registration.
Do need a major credit card, drivers license and proof of insurance for vehicles.
As to the sticker losses... 3 on two different trucks in the last 7 years.
The new thing is thieves are taking the entire plate.
Last summer in the Hospital parking lot I noticed a family... man, woman in a folding chair and two small children changing a tire on their older Honda... what I did not realize is they were systematically stealing all the tires and wheels from another Honda... the victim said her husband had just put on a new set of Michelins two months ago...
Crooks are getting very bold and often not much Law Enforcement can do...
As for the stumps...
I used the backhoe and dug down around the 36" dia stumps and cut them flush with my chainsaw... I've got 3 chains that now need sharpening... much less expensive than the stump grinder and I will just cover what's in the ground with 6" of dirt...
