This is a bit of a tangent, but I noticed two painted utility boxes at Church and Duboce (not my picture): http://sf.streetsblog.org/wp-content/up ... C_9732.jpg
Depending on their size, this could be a fun thing to do with the Sonic boxes.
I have no idea what it would take, nor do I mean to complicate things further. It just struck me as a nice touch that might also make people feel better about adding boxes.
I see that (un)Clear Channel installed a "bus stop" as part of the transit modification that happened there so that they could pollute us with more ads. I think those need some wheatpasting.
I'll also agree and say that it would be a welcome change is Sonic got artistic with any utility boxes that end up being installed as part of a fiber roll out.
