was eating lunch at a shopping ctr and the guys there were doing something different...they had one guy on a bobcat type loader piling snow and then another manning a tractor w thrower who drove around all the curbs and cleaned off the dribble so all curbs were visible! and the lot was completely cleared next they drove a viper w a tow behind spreader to get closer and between the cars....made me think how neat a z turn rider w blade would be to get between cars and obstacles
