Hi folks,  I'll be traveling to Boston in April.  Does anyone know
of any mechanical music attractions that I should see?  I'm also
interested in mechanical things in general (steam engines, machine
shops, etc.) Any ideas would be greatly appreciated.

Also, my John Smith busker organ is progressing nicely.  I don't know
how you people who built one in four months did it, but I'm moving
along.

Thanks,

Bob Meyer (Poway, CA, just north of San Diego)
