135) Bike series (4/10). This is one of those weird mailboxes that’s right out in the open but so easy to overlook. In my 30+ years in Seattle, I have probably driven, biked, run, and walked past this box over a thousand times, but I didn’t know it was there until I started this project. Someone else apparently felt the same way because they felt compelled to write “OPEN” on the side so others would know the box was available to do business.
