i'm kinda new and am having same trouble... i built a step-style bench thing with varying heights for slowing/stopping and tryin technical stuff over. seems to help with the fallen trees and large rocks or obstacles that i occasionally encounter. maybe you could try something like that in your yard... y'know, just to eff with in your free time.

it doesn't have to be pretty. i made mine outta left over wood scraps in my yard. works wonders for the technical ego... just an idea.
