I have trouble believing he worked his hands raw over seven nuggets.  He does tell a good story, with detail.  As for keeping it to himself, think about how hard that must have been.  Is the guy a loner?  Does he have family?  Friends?  He did say he quit his regular job, and also explaines why he only visited twice a year.  Look at what started the California gold rush, and the stampede of people it caused, and the fortunes and misfortunes of many individuals.  Speed is measured with a speedometer, distance with the odometer.  Did he spray paint the stones he used for markers every 50 ft. ?  Thats 211 stones over the course of 2 miles.  720 ounces is 45 lbs, thats a nice round number.  The guy only netted 20 grand, I would say that is not even close to what he should have gotten, even 10-20 yrs ago.  Even at only 70 percent gold.  Thats still 31 1/2 lbs of pure gold,or 504 ounces.  Did he go 2 or 3 times a year ?  What year did he discover this, and what year did he write the story ?  Was it in 2000, or earlier ?  To get  $314,650 in gold, if he sold 504 ounces all at once the price would have been around $624.30 an ounce.  So, his story seems very likely to be true.  I just can't get over only getting $20,000 for 720 ounces of 70% pure gold, or 504 ounces of 100% pure gold.  That's only $39.70 an ounce, What year was gold selling for that price ?  I am happy for that great story teller ( I mean treasure discoverer) but I still think he should have gotten more than $20,000 for 31 1/2 lbs, 504 ounces of pure gold.  Ron
