Feel free to add your photos of the 8-hour marathon open house for the O-Scale National Convention on June 10th. I took very few because I spent most of my time as the dispatcher's desk.
First up, the work before an open house is
never done. Here David adds a starter paint job in "River Gorge", which during his painting effort guests started to arrive and so it became a mini-clinic.

Levi Bacon volunteered to keep trains moving around the layout for guests.

A guest (nametag not visible) shoots a video of a northbound train.

Sarah Grissenboeck came all the way from Austria. She brought her big Sony camera to the open house.

Sarah had the opportunity to run a southbound train behind A&O 4000, seen here, with Rick Bacon as her road pilot.

Ted Schempf, a popular vendor at the train show, came up after he loaded his trailer and ran David's ABBA set of F units southbound with a coal train to be unloaded at the Whiting Rotaside rotary.

Now at the rotary, with its a new Silent Stepper drive mechanism, synchronized sound, and single pushbutton control, Ted unloads a coal hopper.

I'm sorry I missed photographing so many valued guests. When I'm sitting at the US&S 506 replica machine, even a couple trains keep me busy.
