John,
You know, we talked about the cassettes way back in the winter. Yes, I think that could work. I get a one track mind sometimes, so I am glad others are here to remind me or to bring up new ideas. Yes, I think a yard in the laundry would be awkward for trains and laundry. I agree, any savings of money helps.
I have seen the 4-way turnout, and that is a good idea too.
