Andrew has a nice, long-awaited post unlocking the Twin Cities street alphabets @ streets.mn: When You Plan, You Begin With A B C :
"I was driving through Uptown with a friend in 2004 when it hit me: these streets are in alphabetical order! As a visitor I was impressed by such orderliness; a month later I moved to Minneapolis (not because of the street names—or at least, not entirely because of them). I learned about the second alphabet while visiting friends in Linden Hills, but it wasn’t until several years later than some random Google Maps browsing revealed not two but eight (okay, maybe just 7 and 1/13th) sequences of alphabetically-ordered street names extending west from Aldrich. By this time I also knew of the presidential sequence in northeast Minneapolis, and more map browsing revealed some others."
