Is it a bad idea to use railroad ties for riprap? I know they come with some kind of oil on them. I was thinking about using them sticking up and down. Kind of making a retaining wall of sort. I would like a edge so it drops off from zero to like 4 feet. I know just a dirt bank wont hold up after years of waves. Any ideas or suggestions ? And please if its a stupid idea just say hey dummy that's not a good idea. I'm not planning on doing the whole bank like that just like maybe 20-40 feet or so.

The people who say I can't do it can just sit the @^#% down and watch me. Friends call me Rusto I also subscribe to pond boss mag. http://forums.pondboss.com/ubbthreads.php?ubb=showflat&Number=504716#Post504716
