For the second year in a row, PennLUG was invited to display our train and city layout at the Lego Kidsfest event in Hartford, CT. Unlike fan-organized events such as BrickFair and BrickWorld, this was a promotional event was put on by Lego (partnered with another company) and geared toward children. I hadn't attended the first one in 2009, so I wanted to try the one in 2010. We were compensated by Lego for the event, including hotel and meals.
We were busy for the whole event - setting up, tearing down, answering questions and keeping kids from touching the layout (we need Plexiglass in the future). It was actually very tiring. I'm not sure if I would do it again.
