Dave you sent me a piece of the MB wood. What is your source for that? Some local business? I can't say I ever saw an Indian pallet. A lot of Asian stuff, and a lot of times it was on Mahog, or some other pretty wood. I'm not sure if it was chemically treated, because I never had a direct source to get any of it.
Younger I worked at a Sears store, and on the dock we got a lot of pallets, but taking one would have probably been your job. They used to swap them with incoming truckers, so we always had some in stock, but not too many. Daily we would tear down pallets, and remount goods to go to a department, so they were always in motion.
Do the MB pallets have any warning labels on them?
