LOL I was thinking the same thing, only more along the lines of it letting you know where they were! LOLis it a Radio transponder that you bolt to a table and then set your kids down after sk00l to do their homework, and if they move more than 2 metres away their Shock-Collars activate?
Well, you can forget that souvenir I was going to bring you!...Barbara... I have heard that one before!!! LOL!
Have fun on your trip if I don't get to speak to you again before then.
