Did the previous paddock owner feed his cows hay /silage? . The original looked like a feedout rack. Now you can start one of the hardest things to teach kids. Tidyness is next to godleness. Without that teaching the bike rack is doomed to a short life. It is always too far away, in the wrong direction, I was late for tea,the novalty wore off etc. Have fun, don't let them see you laughing at their excuses to often.
