I was playing with ours last night on the SS, we did not get the technique down, but attribute some of it too how dry it is right now, it is somewhat akin to digging in concrete.
Sounds great on the family, Dean and I have been riding Tues nights with some other Trials guys here in town, it is cool, but my life has been a circle around this new to us house. We are now shifting too working on the old house.
We have not had the ER trips (knocking on some serious wood) but Dean has been practicing juggling on the 5' uni while riding on the gravel........... He also is getting those high speed 4th gear running wheelies down, and paid the price a couple weeks ago when he missed the brake
Thought that was going to be an ambulance ride but he shook it off.
Can I invite myself up sometime to learn about your tree farm? It is something we are very timidly toying with, although I guess more then likely we will be a "shrub" farm.
Oh, and added on edit, I can offer you a very special deal on a tree sling for basketed tree's we have been making. Has a hook that goes on the bottom of the basket and a sling around the trunk, they work great, we saw our nursery guy use one, so I made some up, really helps moving the big trees.
