I think both rent and land prices are driven by what corn used to sell for. The guys paying the high prices are doing it with the money they made with $5.00 and $6.00 corn not $3.00. If we keep having $3.00 corn land prices will come down. It takes a little time to spend the  money that was made with $6.00 corn. Most farms can lose money for a year or 3 and still be OK but not as many can lose money for 5 or 6 years.
