Yep, they did jack them up a bunch but probably because the daily ranges have gone through the roof as well. The ranges are so large that many of the grains have become day trading markets (with some of the biggest moves coming in the overnight sessions!) As a result the mini-markets have become the new haven for the small spec. Fortunately commissions have come down a bunch as well, so you can actually afford to trade them and not lose your shirt paying the broker.
If you're going to lose your shirt do it the ole fashion way...in the market! ;-)
