I sense an ExI-Bay ROAD TRIP!!! :)

Raph, I would like to see if we could line up a visit some time for a
few friends to check these out.

ExI-Bay: Maybe schedule it for the same day as a Tactile Dome visit at
the Exploratorium. Hmm, and sushi. That takes care of at least three
senses. Can we pack the whole set into one day? :>

Would someone on ExI-Bay do me the courtesy of crossposting this MS
there? Thanks.

Mike
