Riding Razors at night during Hunting season

I have a hot topic that has been an issue at my camp that I need help on.
During this past deer season we had members that would go out from about 9🙂0pm till about 1🙂0am riding their Razors all over the property. The riders say that it doesn't bother the deer while other members say that it does. I believe this is the first year they have starting ridding at night and this was also the least amount of deer seen or killed on the property. Only 8 deer were taken this season on 1800 acres. Can anyone help with this argument? Who is right? Should night ridding be not allowed during hunting season?
