Mine too.

Perhaps I should revamp the whole system and come up with a better
organization scheme for the lists?

A PA traction list is too all-encompassing? 

Basically I want to avoid irritating people like Ed who don't want a lot
of extraneous traffic...

I don't knock it, I got tired of banging my head on Windows and MacOS long
ago! This list runs on the oldest of my machines, running SunOS UNIX since
1994:-)

At any rate, as for maps and aerial photos... currently I have just over
half of the maps covering PA that I brought home with me yesterday, and
I'll grab the rest today. The aerial photos are considerably larger
data-wise, but it looks like the maps can be split such that if I leave
them compressed as they are now, 4 CDs will cover the state. I have a CD
recorder attached to my Linux box, and can quickly master a standard ISO
9660 data CD. Perhaps I can find some Windows viewer software, try it out,
and sell you guys CDs of this stuff if you want it at my cost? ($1 a CD
plus shipping; The $1 is literally my cost for the media.)

Well, this should be taken off-list, and those of you who care should
reply in personal email, I think...
