Where in Natick?

Since it's my first day, here's an easy one.

Where in Natick can you find this red box with the words "city cables" on it?

Many of you have probably walked right past it, especially if you frequent the downtown area. 

So leave your guess in the comments section below and prove how well you know Natick. If you guess correctly, I'll award you with one Patch Point, which is redeemable for bragging rights.
