Spotted in Boston: Street Art?

I enjoy reading a few blogs about street art so I'm always on the look out for good examples wherever I travel. In Boston the other week I spotted this billboard that I had to give a good long look at to figure out if it was just falling apart or if someone had done this intentionally. In the end I figured it was just something that happened, but I love the idea that the rough/dirty reality is being revealed behind the pristine image reminding you that you "can't buy happiness".

Spotted in Boston: Bicycle Tickets

Apparently at MIT if you don't park your bike in an appropriate place (this one was just left laying on a shrub) then you'll get a ticket! I'm not sure how they're enforced, but I'm impressed that they're even around long enough for someone to find them considering that bikes left unchained where I live would be gone in seconds!

Has anyone encountered these anywhere else?

Spotted in Boston: Clear Signs

Apparently Bostonians don't want people to just blindly follow orders, since they went out of their way to explain the reasoning behind the signage I encountered there...

Bird sign found in Boston Common.
Revolving door sign found on MIT Campus.

Spotted in Boston: Bigfoot Research Institute

In my ongoing quest to visit all of the 826 Stores I managed to stop by the Greater Boston Research Institute on the one day I had to explore Boston on a recent trip up there. Sadly it was a Sunday and the Institute was closed, but even from the outside it was very entertaining. For those of you that aren't familiar with the 826 project it was created, in part by author Dave Eggars, to facilitate creative writing programs for kids. The first location was 826Valencia and its adjoining Pirate Store in San Francisco.
Like the other stores the space is not in the center of town and none of my friends in the area had even heard of it! Needless to say my friends that brought me there, plan to go back when it's open to get some official GBRI tin cups and specimen jars!

Seriously, if anyone wants to start an 826 program in Richmond, VA or nearby I'm officially volunteering to do the design work!
