First, I've neglected to mention that I do have the GIS data that the City of Billings promised me. First thing I noticed was that there wasn't anywhere near as much as the GIS manager tried to tell me there was; second, it didn't take anywhere near as long for them to provide it as he suggested it might. I've had the chance to go through and have a look at it, and I'm actually somewhat impressed with the attention to detail and thoroughness the city is showing.
Second, as regards my Good Deed, I got a letter in the mail a few days afterwards -- from the pastor of the church the lady goes to. In it, he thanked and congratulated me on being a decent human being (my words), and wished me well. Apparently, she told pretty much everybody in the congregation about what happened.
Finally, my blitzkreig of eBay doesn't seem to have done the slightest bit of good; not only did the stuff remain listed until the respective auctions ended, but even MORE unrelated crap turned up. Between eBay's unresponsiveness and PayPal's willingness to summarily freeze accounts without explanation, I'm about this far from telling both of them to get stuffed.
So, it's been a mixed bag since my last post. :-)
