GCA,
We are building a mountain course and I have some ideas about the slopes around some holes that could be a safety hazard for golf carts. I really deep inside believe that no one can be so dumb as to drive a golf cart over the slopes but, for safety and liability we have to address these areas with some type of natural material that creates a barrier.
The use of natural rock all the way down the length of a fairway is just too much and I would rather use something low profile maybe 12" to 18" tall max. Anybody have any images that you could post showing this type of barrier? I am considering using a railroad tie standing it tall about 8" back filling soil behind it and growing native grasses and wildflowers beyond the railroad ties about 2' tall. The railroad tie would be anchored using rebar and would allow the rough to grow right up to the edge so that a weedeater could easily maintain a clean edge line.
