If it were me, I would still use your garden hose, but would connect it to your "cold" faucet for your washer (to prevent the tap from freezing due to outside temps) and then just drain into an isolated area of the back yard that people don't need frequent access to. Unless you're in the middle of a big cold snap, the ice shouldn't stick around long.
Otherwise, whenever i'm running my exhaust water from my CFC, I drag the hose across the front yard, and tuck the end of it directly into the runoff drain in the street curb. Then the water is in nobody's way.
If it's cold enough outside, you could hook it to the sprinkler, and wind up with a hell of an icicle display for the neighbors?
