A full day of cutting driftwood into stove sized pieces, then stacking it in piles to be rained on. Over the next 3 to 5 months the rain will clean 90% of the chimney-corroding salt out of the wood. It will then require a minimum of 3 additional months of drying time under the tarps before it can be burned.
In other words, an enormous stockpile of firewood that probably won't even be used until sometime next winter. Yes, my conception of time is changing.
