Good bye, Tree

The tree-guy arrived yesterday and took down the maple from the front of our house. I'm a little sad that we had to chop down the tree, but it had been dying for years. This spring it looked especially unhealthy, with very few leaves on the branches. We were worried it would fall into the house and I was more than a little nervous about the carpenter bees that seemed to be feasting on several limbs.

And it figures, with the location of the trunk above the stone wall, there was no way a stump-grinder could get there to grind it to the ground, so now we have to figure out a way to get rid of the stump. Any ideas?
