I used to live on another Somerville "avenue" with a correspondingly named "road", though in my case the doppleganger isn't anywhere nearby.

I work as a consultant who gets paid through the mail, and every so often a new client would say "Hey, I mailed you your payment but it came back 'No such address!'" My first question is, "Did you address it to Linden Road instead of Linden Avenue?" So far, that's always been the cause.

Just the price of working in a city so dense that it needs several layers of street-namespacing...
