I Would Be Appalled
One of the things I'd like for my garden is a small river of lava, if only to have a convenient place to discard the furniture I no longer want. The only downside I can think of is that I'd occasionally see a bunny fall into the lava. I hate seeing bunnies falling into lava! Nothing ruins an afternoon like witnessing a bunny in lava, unless it's seeing the lava rise up, form a clawed hand, and proactively swipe a bunny from the green grass of safety. Christ - loosen up, lava river! Patience. Don't be so grabby.
