I've got local cash bid charts going back well over 20 years, probably could source some into the 1990s.  It's a fact that basis appreciation/carry have not changed anywhere near enough to cover the increase in cost of storage structures now vs. say circa 2006.   That's not to mention how much since the Wuhan Flu the interest cost for both construction and operating monies have gone up.   

The value of a place to unload at 10pm on Saturday when a storm is coming in continues to be high but hard to put a dollar figure on.
