As far as picking up unsecured networks, it depends on the legal environment of the country in which you are. It can be compared to a thief walking into a house with an open door. There is no breaking and entry, but it is still illegal to go in and take in stuff.
In terms of your safety, if your network is secured and encrypted, you're not at risk immediately. However, you could consider adding MAC address filtering to your setup to make it even less attractive for others to even knock on your door.
That's the short of the story.
