I'm about 100 miles east of Des Moines, Dave. I get over that way occasionally, but have no plans in the near future. If I do, I'll give you a shout.
I need to find more helium weather balloons and 1/8" steel cable to finish constructing my black helicopter defense system, though. I figure a sudden release of dozens of those balloons tethered by a few hundred feet of thin steel aircraft cable might pose a problem for helicopters. Maybe I can even get some of the old Macy's parade balloons, too. . ? Hmmm... I could send Underdog, Tigger, Spiderman, and all the others up, up, and away to deal with those pesky choppers...
