They had a District Merit Badge Clinic at our chapel on Saturday.  My friend Roy was doing railroading, so I invited myself along.  I had just finished the plexiglass cover and new backdrop.

One of the requirements involve doing a shunting puzzle.   While one scout ran the layout, another worked a problem on the computer.  Most of them caught on pretty quick.  Only one was able to complete the 
computer version (mine is a bit easier).

Roy is an "O-scaler" and has quite a Lionel collection.  The scouts helped set it up, wire it up, decorate, and run it.

Part of the merit badge is knowledge of the different scales.  Here my N-scale WPRR 2302 "Adair Village" contrasts Roy's O-scale FA unit.  Most of the kids were familiar with HO-scale, which is in between.

They gave my layout a good test.  They seemed to enjoy it, and nothing got broken.  A good day all around!  I was glad for a chance to show it off.
