I originally started my auto-x journey in the San Diego region and I know the use of temp numbers/number ownership worked well in that much larger region than ours. This past April's event one of my competitors was another black Focus ST and literally ran right behind me and if I didn't have my numbers, I could easily see things getting mixed up, let alone the plethora of "like" Miata's so I would agree with the need/use for numbers as well. I know that the current system works when it does and then there's instances like this past event when its a cluster...... If remember correctly, isn't our club from a financial stand point in an overage? The temporary numbers would be a drop in the bucket in terms of using up an expense. Also we've graduated to a medium region and have made some great leaps and bounds, this could be another one of those next steps into making this slightly better/efficient.......
