So, yes you will need to winterize by the time the temp falls below freezing for more than a brief period (a couple of hours at 30 probably won't hurt anything but a few hours at 25 could freeze some things). Even though you have drained the tanks, there is still a LOT of water in the lines as well as the water heater and the lines, faucets, fixtures, toilet, sprayer hose, connectors, water heater, etc. can all freeze and burst either during the winter or in the spring when water pressure is applied - some of which may be hidden within the walls or under the floors. Even small droplets can crack a fixture.
There are multiple methods for winterizing. Dealers will do it but it is not overly difficult for a DIY-er to do yourself in an hour or two depending on how you do it. Please see here for lots of information:
