I hope you find some. I would like some too, I'm closer to Franklin though.
The best plan is to look at small manufacturing companies' back parking lots to see if you can find a stack of pallets. Then go in and ask if you can have them. They usually have to pay to have them hauled off, so they should be free.
I once piled up way more than would fit in my truck. I lived nearby, so I hooked a chain to the stack and dragged them home. Lots of sparks from the nail heads. I wouldn't recommend that. Cops don't have much of a sense of humor these days. The ticket could be expensive.
You will need a crowbar, cat's claw nail puller, superbar, large pair of channel lock pliers (or better yet, a good pair of fencing pliers), and the kind of energy that I had 30 years ago.
Don't forget a good pair of leather gloves. Wood used in pallets is usually of low quality hardwood, lots of knots, splits, cracks, and SPLINTERS. Disassembly will create more splinters.
From my past experience, you will save some money if you don't have anything else to do with your time, and if you already own all the tools. With the price of fuel, if you have to do much driving to get the pallets, you can end up in the red on your project.
I still have wood from the pallets I disassembled back then and, occasionally, it comes in handy.
Since the slats on a pallet have nail holes on both ends and in the middle, what I finally settled on was to cut along the edge of the outside 2x4 supports with a saw. This cut off 2" on each end of the slats, but removing them whole usually resulted in accidental splitting of the slat end, so I thought I came out ahead. Then I used a piece of hardwood 2x4 as a buffer to the slat and pounded off the slats from the center support with a 2 pound sledgehammer.
By hitting the buffer instead of the slat, the slat is MUCH less likely to split.
To salvage the 2x4 support pieces, you can remove the nails, or cut them off flush with a good sawsall blade, or split the 2" slat stubs off and then pound the nails down into the 2x4's.
When you go to use the lumber, don't forget that the salvaged lumber can have nails imbedded in it. Don't use an expensive blade to cut it.
Good Luck,
John
