Snow walking stroke therapy

We have a measly 2 inches of snow here. Yesterday I walked for 1.5 hours on the trails next to here, with snow globe snow coming down. This is barely effective as a useful walking therapy. What we really need is 12-15 inches of unbroken snow. I remember trying to walk when the snow was over my knees. That would be for advanced patients. The requirement would be to posthole every step. This would force recovery, any compensation you would try would fail, probably dumping you into the soft snow. Your therapist would require releases from getting snow down your neck, etc.. And snow angels would be wonderful, all that abduction.
