It looks like Evaline Waters, a River Heights resident, is knee-deep in trouble. A huge corporation is suing her for her land; they want to tear down her house and put up a warehouse. And documentation of the zoning law that would protect Evaline's right to keep her land is missing. Figures! <P> I've got to find that document, but it's hard to focus on the land when I'm cruising at ten thousand feet. See, Ned and I are taking flying lessons, him with Colonel Lang, a friend of his family, and me with Frank Beltrano, an instructor at our local airport. It's a good thing I'm good at juggling more than two balls at once. Too bad I'm not the only one.
