Replying to Weirdest thing you grinded on skis.

We just had our first snowfall here in Brigham(Qc) and I immediatly felt the need to grind something on my skis. Having no setup at home, I was looking for something quick and easy to calm my envy. I ended up grinding an old mailbox pole half mounted on a wooden platform.

This made me wondering if I was the only one to grind weird things before the season and if I'm not, what's the weirdest shit you guys ever grinded ?
