i met some wonderful people and spent the whole time with a massive grin. so worth it.
photos are here
the layout took over an hour to set up and didnt match my plan exactly, but it fit on the table nicely. i also took my scrapbooks and the parents spent heaps of time looking through them.
one woman came and sat by me while she looked. she had two disabled sons with her, and i offered to clean out their engines and will also give her some trackmaster/tomy adapters if she comes into work.
all in all, it was 2 great nights and i wish i could do it all again.
