Don't forget to dress properly when handling the RR ties. Creosote will burn your skin! The first time I landscaped using RR ties (a long time ago) I ended up with welts around my legs where the top of my boots collected sawdust from cutting w/a chainsaw. I wore gloves but wiping the sweat off of my face gave me burns that felt worse than a bad sunburn. In short, wear gloves, long sleeves, long pants, etc. and watch what you touch!
