Well, I unnerstand that! We pretty much can do the same thing here too.
I have perfectly level ground between the house and garage so my chance of doing a dixie is minimal.
The problem is with the little Wyatt dog. He has low clearance and can't make it up hamburger hill to draw his mud!
He can only make it out to the back yard and that totally un-trains him from pooping on the lawn come summer! It happens every year. Karen's dog, Zoey (Norwegian Elkhound) is a freakin ATHELETE and can clammer up the iciest hill like a mountain goat! I am hoping that she will break the trail for Wyatt!
BTW, I actually made progress on the plane today with all that was going on! To top it all off, school is canceled for Monday so I have another day to tinker!!!
