I'm surprised nobody has mentioned the unsurpassed ability of R22's and R44's to leave beautiful burn spots on otherwise nice lawns. No, you wags, I don't mean because of the "inevitable" crash, I mean because when sitting there doing the 3 minute cool-down routine all that cold air that the squirrel cage fan is sucking in to cool the engine is being ejected, now burning hot, straight down onto the ground. It really does do a fine job of turning green grass brown, and can actually be a fire hazard when landing in tall, dry grass.
