I would agree this is our starting line at our local track. They might scrape it once a year. They do not have a drag. And they will use the sweep dry when someone drops oil from the round around track.. and let the drag cars dust it off if you can believe that and it's open every Thursday night and they sell out 250 Tech cards two street cars.. I don't know what real track prep is.. are good track Fontana has a concrete Launchpad and his built in a parking lot that goes uphill
