I out together a new rock obstacle with my tractor yesterday and had a chance to try it out on my EVO and XTrainer this evening.  Rock (which are rare around here) is about 5 feet long, and I pitched it such that it is around 4 feet high.  Just enough that I don't go over the handlebars when coming down it.  Will give me a great obstacle to try different methods coming up.

 

Added a small rock garden to my trench, and a few other new rock obstacles.

 

My 4 yr old grand daughter asked if I could ride on a piece of culvert laying over by the fence.  Told her to help me move it and set it up as a balance beam and crossing obstacle and we'd try it out tomorrow night.  She's pretty good operating the front end loader and grapple on the tractor so helped me move it and a couple of stabilizing railway ties into position.  Should be fun!

 

Some fun with some buddies last night.  After trying obstacles on the EVO, the XTrainer just has to try the same things.
