meralgia: It really kills me to do this, but it's the "responsible" thing. A question was posed, an email was sent, and now (fully knowing the "legal" answer), I feel that I must archive the cache. What baffles me is that Pfalstad's original cache lasted a little over a year without someone raising the question of legality. This one lasted, what, a month??
Anyway, if you're interested to hear what the Public Works guy sent, lemme know.
