This is a little embarrassing since my last post featured what has to be the coolest ski groomer ever. Ours is decidedly non-cool.
We drag a bed spring behind an old Polaris snowmobile. Round and round we drive the sled, packing the powder, and then round and round again with the bed spring to level it all out. Simple, practical, and even effective sometimes. It's an okay way to groom trails, and a really good way to mess up a bed spring.
It has been a long winter.
