Cell phones take lousy pictures... I really don't reccomend using a camera since its hard to take a good shot without exposing yourself.

You just want her address is all... I don't think one of your friends will mind following your H when he leaves your home to see where he's going.

I believe PUP here hid a GPS enabled CELL phone in his car when his wife snuck out once to find out where they went... you could try that...

Pup you may have more to add there...
