I was flipping through the Signals catalog (even though I have zero interest in touchy-feely warm-fuzzy inspirational decor and doodads) and came to a page where they offer geography-related items, including shirts and a doormat customized with one's latitude and longitude.  Kind of a neat thing to a GPS-using guy like me, that doormat, and they even offer to  figure out the coordinates for you - just give them US city or zip code. The only problem is that their example is wrong twice!
The coordinates are shown in degrees and minutes, with the example doormat reading "Welcome to 40°75'N  73°99'W" which looks fine until you consider that there are only sixty minutes in a degree.  The values of 75' and 99' are completely invalid.  Maybe they should stick to candle holders and wind chimes.

Just for grins, I punched the corrected coordinates (41° 15'N, 74° 39'W) into Google Earth and found they point to a farmer's field in the northernmost corner of New Jersey.  Could this be where Jimmy Hoffa is?
