It is hard to fathom the complete and total junk that someone is in love with that they will spend thousands of dollars over time to store it while it continues to rust away. I have seen some of that junk myself while looking at other things in a rented storage lot. Enclosed spaces are even worse for crap that folks just can't throw away. Visit with the owners of the storage units/goldmines for some stories.
I once went to look at an 80's Dodge pickup for sale that ended up being totally rusted out from one end to the other with both doors broken at the hinges too. I figured he had spent $2,000 in storage, and he was broke on top of that. I gently tried to get him to cut his losses, but he wouldn't.
