I don't know what it is, but I'm having a heck of a time getting firewood this year. I've been trying since mid-winter. My normal supplier jacked his price up $70 more per cord than last season, so I bailed on him. Most of the numbers I call, I leave a message multiple times and get no return calls. Others I've finally contacted whined about delivering it so far (20 minute drive from their piles). And one guy I finally worked something out with promised me delivery in March and I'm still waiting. Now he's promising late June or early July. I have this nightmare of a brand new Jotul Oslo on the hearth, and no wood to put in it this winter.
