Both seem like good practice but if you waste water, or leave your car unlocks so bad guys can steal stuff, that's a bad idea.
Rye PD has reported "Our community along with surrounding jurisdictions is experiencing an increase in larcenies from motor vehicles. So far the suspects have only targeted unlocked vehicles. Please be sure to lock your vehicles, remove keys and keep all valuables out of sight. Most of the thefts have occurred overnight, please contact the police department immediately with any suspicious activity."
And on the water front, our water supplier Suez is reminding residents via a city communication that emergency out door water restrictions remain in effect. This means "(Rye) customers still cannot use irrigation systems due to a drought which impacted water supplied by Aquarion Water Company". Suez purchases water from Aquarion and their reservoirs located in Connecticut.
