Sledders best friend in the cold is clothing. That fact can't be changed but it does give them the advantage on being hard to identify. Burka in the bank has been made to be acceptable. Truth is damage from a snowmobile driven by someone on farmland can be harmless. Most farmers don't care really but sledders hunt for powder and fields where they are sheltered. Trouble is those areas are by farm yards sometimes. Small shrubs can get chewed up and the noise factor. Back in the early 70's you had to have a yellow number on your sled here. I still remember 46 on dads old Massey 440 WT. and I can't remember on the 300. They were 4" high numbers that were reflective and easily read on the side of the hood. Snow covered license plates weren't an issue back then.
