Some neat responses, starting with PH and going down the list...
As more than one person mentioned, their mess is their responsibility.
Their room, their games, putting their cloths away, making their lunch, etc...
Scott, pretty cool making the boat project part of the deal.
Especially since it was fun & work at the same time.
I am sure cleaning the mess in my garage was not as rewarding for my kids
– but they learned some things and had a little fun.
HB, probably the closest to our system.
But, we throw a “rate” out sometimes (like this time).
FatDog, yes, it is amazing how things pile up.
I can’t believe I have a floor to look at now.
Sorry, can’t FEDEX them out
I have thought about rerouting the attic fan more than once – but haven’t added a duct yet.
Strange, the exhaust air doesn’t seem humid – just hot.
I don’t think I have shortened the life of any tools or electronics – not that I know of anyway.
LBS, you are right, I guess I didn’t pay too much for the help.
And it was nice to have the boost to clean the garage & nice to see them working hard with a goal in mind.
Thank for curing my curiosity everyone – as usual many different responses w/some common themes.
BTW, they didn’t know, but they would have had a new DS game sometime before we go on our “road trip” vacation next month

They are great kids (if I say so myself) and we don’t mind spending a little on them.
