Does your mail man ever get lost? Maybe he should switch from Mapquest to Google Maps. Or you could do it for him—sort of. Google Maps envelopes (only a concept at the moment) would let you send snail mail through a button right in gmail and print envelopes showing the route between the two addresses. The only flaw with the design is that the from address would have to be west of the to address, unless the envelope isn’t strictly oriented with North facing up.
