Ma wee cairn...
This is one of my lockdown social experiments. I started building this cairn in our wee woodland walk to see if people would add to it. There's been a few additions but more demolitions than that.
I dutifully bring a handful of rocks on the dog walk and generally find at this stage that someone has dutifully demolished it. Little do the demolishers know they are generally helping me out at this stage. I usually bring a handful of fist sized rocks and one large foundation rock. The demolition lets me put the big rocks all in the vase and re-organize it around them.
I'm hoping it gets to a stage where it takes too much effort to take down. I certainly won't get bored first.
