On Rain Barrels

Every time I do something new and exciting to the Lair’s roof I think about rain barrels – then I chase something shiny and forget it till next time. It’s never really been a serious matter to me because I don’t normally have to work hard for my water. I have the luxury of mostly-dependable water at good pressure and I don’t garden, so why bother with a hundred gallons or so of buggy slimy goo? Two simultaneous developments put the topic a little more seriously in mind at the moment.
