How to reopen a dragstrip?

Update--I forgot to mention the memorial plaque at the finish line in remembrance of a January 19, 2013 tragedy that took place at about 3:00 AM. A 27 year-old Norman Zain Verduzco Zaya, who was the "starter" for some very late night unofficial, unsanctioned drag racing, was killed while speaking to the driver of one of two cars waiting at the start line. A vehicle from the previous race returned down the drag strip, coming down the wrong way at a high rate of speed and ran him down! I have never heard of such a stupid, irresponsible action. Go figure. May the poor kid rest in peace.
