I've noticed that this is a New England thing. Driving up for the first time, I got lost repeatedly. Signs were placed too close to exits, hidden behind trees, etc. I came to the conclusion that there must be some local aversion to proper signage, probably based in the area's age and relative insularity. "Keep things the way they are and have been for hundreds of years," and, "If you're supposed to be here, you'll know where you are," attitudes, respectively. Boston, Providence, etc. are cosmopolitan, but I'd wager that the people who control public works iniatives are decidedly not.
