So B and the kids were enjoying watching the groundskeepers blowing out the automatic sprinklers (in time for the cold weather - ugh!) when suddenly a large geyser-like explosion erupted from somewhere under our footpath. It blew a rather sizeable hole...fortunately no-one was standing nearby to get bludgeoned by the dirt and gravel that went flying.
It seems there was a small leak in one of the pipes that got completely blown apart by the force of the air that was pumped through them. Happily, they came and fixed the section of pipe without too much damage to our walkway.
And apparently, the landscaping guy commented on our lovely footpath....why thank you, we rather like it too. ;}
