I had planned on no-one needing "landings". :)
Grass is great. There's no better place to practice pack riding skills like bumping, touching wheels, pushing/pulling, etc. I don't know many tris where that stuff becomes necessary, but good bike handling skills are always beneficial. It might be good for practicing flying mounts/dismounts too, as long as it isn't too bumpy.
