RR ties rot away quickly, and the 20 year lifespan that was mentioned was an unusually luckey and long lifespan. (Their treatment is designed for out-of-the ground applicaions, resting on a well drained foundation. If you bury them, you might as well use the cheap pine or popular that's sold as dimensional lumber.)
and it looks better than hokey looking rr ties.
I think you could make your point without using gross exaggerations like comparing treated railroad ties to untreated poplar or pine. And saying they look hokey.... Why would you want to insult those of us that have them in our yards? Some of us obviously like the way they look. I can think of a lot of words(not very nice words) to describe your post here BUT I'm not going to say it out of respect(even for someone that shows none). Have a little respect for others......
"Hokey"? Several apartment complexes here in town , designed by architects, had RR retaining walls as part of the design , "some" people like the looks...many homes have them for garden designs too (which this case would be)....personally I had a split one ( in half , the long way) hanging from chains with 10 holes driled out , candles in those holes, makes nice decoration..I guess all "tastes" arent the same...
