 I've landed N42BK (a LNC2/320) on grass a couple of times. It was uneventful.
My speeds are identical to Don Barnes, but I have great elevator control and
can hold my nose off and lower it gently.  Otherwise, I'm in agreement with
Don. I think your risks multiply and if the surface were unexpectedly rough or
soft, nasty stuff could happen.
