I bought a snazzy nozzle for the hose a few years ago, since the old nozzle leaked, but I almost never actually use the hose for anything. Last night, though, I cycled through all of the nozzle's settings, using the mist to water the bushes near the door, using the spray to get most of the lawn near the house, and using the narrow stream at various angles to get some water into the corners of the yard. It wasn't a 100% thorough approach, but it should help the lawn from getting too parched.
Even if it's not perfect, I don't want my lawn to end up looking like some of Cornell's is starting to. (See right.)
As I was getting the hose uncoiled, I noticed the neighbors had a sprinkler going. A sprinkler would also make a fine mechanism for cooling off humans. :-)
