Some really good suggestions, some not so good.
The only problem is everyone of these ideas involve manpower, from the clerks in Toronto keeping track of where a hut is to going through a few thousand files to match a hut to a picture. any added workload either requires more funding or takes individuals away from what they are paid to do when adding functions in the workplace. Then we will all complain that are user fees are going up as well as taxes to pay for CO's towing huts off the ice, if safe to do so, then storing them at some magical location. Then we will complain there are even less CO's out there or will find something to complain about. I'm sure the gas plant will eventually get into the mix. Then of course the cost to rent a hut will go up, I'm not sure the operators will tow those huts off the ice and store them for free.
I still say lets all have a big bonfire and burn them. Hopefully nobody on a sled after the 16th goes into the big hole melted in the middle of a lake.
If anyone sees some jerkoff taking off registration numbers or painting over them shoot the idiot. Those huts will have been there all winter usually, most everyone knows the neighbors. Post the pictures online next March on a hall of shame site or the like, Facebook, all the forums, social media is a powerful weapon for solving crimes in this day and age. I'm sure someone will recognize who's it is. The Ministry should start a Facebook page next year with the lakes name and a pic of the hut.
A real problem is if iceout is before March 15th, then what? Is there anything in the regs that require a hut be removed if a melt is on, then what if it can't be safely retrieved.
But I still vote for a bonfire. Burn them I say, burn them all.
