Yeah I did, the plates are registered to the other house, you don't park it there. Who cares? Noone can easily come across that information anyway just via plates. The point still stands, someone might see you pulling into said house, yeah a long shot, but stranger things have happened. And it's not that much effort to go steal it now that you've told everyone your security measures.
The long and short of it is, you most likely don't have anything to worry about. But I still wouldn't be posting details like that... you just don't know.
