doodle looks good, Laura.
To tim’s question – is your yellow area the spot where people would be able to “walk into” the display? I can see Tim’s concern, though I don’t share an intense concern myself, but I wonder if there’s a way to expand the stanchion gap to decrease that risk. Another concern is that a lot of that table space is going to have to be used for train track loops, since there is not a continuous table to make 1 track loop.
