I was informed that the Cow sim, where 'Chasm' had been installed, was due to be sold on September 1st. So, regrettably, I had to take down everything the night after Arthole Season 2 opened.
'Chasm' itself wasn't much -- only about 500 prims in all.
'ORIENTATION' was built on that sim as well, which took up about another 3000 prims.
So, in all, I had two major installations on the sim that took up just under 3500 prims. Not bad. I have learned to be rather frugal with prim usage, though.
I wasn't really too sad to take down 'Chasm' (though I wish I could have left 'ORIENTATION' up for a few more days so that Arahan & I could film it a bit); I was ready to say goodbye to it and move on.
Thanks again to everyone who contributed to, helped with, visited, and otherwise supported my projects on the Cow sim.
