RE: What safety related rules does your club have that are really good?
Yeah, if you are in that part of So Cal I can understand the fire hazard. But, there are some wonderful varieties of Bermuda Grass that will grow there. Even in desert like conditions.
But then you will have to buy a riding mower and someone to mow.
Why not just keep a couple of fire extinguishers around for when one of those LiPo powered models catch fire. Gas would be a lot safer.
