You can take a chance and drive into Shur-Gain in Truro, the pallets they don't want they pile up next to the road for anyone to take.
In a couple of days, if you truly want it for scrap wood, and don't mind pulling them out of some weeds, you can come and get what I currently have sitting in my yard, which is about 13 pallets. They all range in age and condition. I can even send you pic if you want. Let me know!
