Around here the FBOs that rent taildraggers only allow operation on grass.
Grass causes no additional wear and tear and in fact is easier on tires.

We were talking about the rule at flight schools/FBOs prohibiting
landing rental aircraft on "unimproved" strips -- that encompasses
grass/turf and/or dirt and sand, or anything that's *not paved*. I did
not disagree that grass is easier on tires.



The operative word here is "unimproved." Usually, a dedicated grass
runway is an "improved" runway; therefore, it falls outside the
restriction. Improved runways include turf, pavement -- even graded
dirt, for that matter.

I've never seen anthing close to an official definition for improved or
unimproved. Can you provide a reference? Does each insurance company
define it their own way? When I owned my 182, the insurance company
knew we were based on a grass strip so we had no such restrictions.
