One of my favorite things to do on my way to work, is drop off eBay packages for my wife. She sells a far bit of stuff on eBay and I just dig doing the post office runs.
I’ve always dreamed of being a bike courier, but that dream has never materialized. I even have the anarchist spoke cards on my fixie, a courier bag and roll up my right pant legs just to try and feel what it might be like to be a courier. It’s what you call living vicariously though your bike.
