I read something interesting this week about factoriy workers in China not returning to work after their new year holiday. Apparently it is a problem in China and the factories have to hire and retrain new workers to replace the workers who didn't return. The article was specifically about toy manufacturers, but I would think it would apply to other goods. Maybe the problems with the tarps were that they were a batch of the new hire ones.
Keep movin', keep believing and enjoy the journey!
