I got a chance at a pair of 16" artillery shells for cheap. They would make great driveway markers, maybe even with illuminated nose cones. Any known dealios on displaying these? Just wondering what 9-11 had for an effect on " dangerous devices"...even tho they are inert. Hate to have a wondering BATF agent accidently spot them...... and then show up with a full team the next day in flak jackets and HK's drawn......looking to arrest the first head that pops out. They did that very same thing here to a guy that was in the biz of hacking TV signals for farmers with the old 10' satelite dishes. A bit overkill I would say!........
