Landing on grass vs. landing on asphalt?
Just picture this; you come in for a landing with one of those directionalized parachute wing things on some good quality grass that is a little bit wet. Ok...it's time to assume the skydiver surfer position and slide on home, back to terra firma, and make a sliding landing, where you come in to land and do a slide-in as opposed to a running step-step step landing.....just like a surfboard on the wet slippery grass.

And, then picture yourself doing the same surfer style landing on black asphalt......ouch....just not the same type of landing!
