Storage of computer and parts in the residential area

I'd suspect that this is due to observability of "big iron" from some vantage point off the property. We've had annoying visits from city folks from time to time, apparently resulting from what one neighbor or another can see from his porch. My neighbor had a problem with his boat, which he parked in his front yard where it's shaded from the sun, and which I certainly like with parking it on the street. Someone didn't like that, however, and complained to the authrorities. The result was that a notice was sent by the city, citing a confusingly worded statute of which they included a relevant portion. It turns out, however, that, though, on first reading, the statute suggests that it's illegal to have anything at all anywhere on your property, what compliance with the statute really requres is a substantial concrete or other "firmament" on which to park the wheels of the trailer, which was easily solved by putting three 1' x 2' paving blocks under the wheels. I'd guess that there's a simple solution of that sort, if you allow cooler heads (your own, after it cools off) to prevail. Dick
