Even if you stop newspaper delivery and mail service, there are still some gotchas that can make it obvious that you're not around. How about those fliers that peddlers leave on your doorknob, or those periodic yellow page book deliveries?

Whether it's a neighbor or relative, nothing beats having a person check the premises every day or two while you're gone. Hey, while they're there, they can water the petunias.
