In case this is real, let me point out that a buyer is required to give an IRS 1099 to sellers of, I forget exactly, about 30 oz. Selling a lesser amount keeps you under the radar. If you wanted to pay taxes to ease your conscience sell individually on eBay and report the income as internet sales. I don't believe that a gov't entity has the right to own land to the exclusion of a citizen finding and keeping something that is abandoned no matter who or what says otherwise. So, the decision is a moral one not legal.
