They don’t have to fly to grass 
Or indeed fly to an airport. I rarely fly to airports. I mostly just land there and go somewhere else. Maybe one could add “grass grows faster” to the negative points in that thread…
It has been a very wet Spring with little sunshine and wind lately to dry things out, I believe lots oft French Grass strips are in similar states this spring.
My base has been usable 90% of the time, it’s just all the water in the air that’s been a problem as in I can’t see through it
