For most people in NYC, if you want something you have to carry it, push it, or pull it with your own energy. I remember when I first moved here I had to watch myself when I shopped. A few times I bought more stuff than I was really comfortable carrying.
A gallon of milk, a carton of Orange Juice, a 12 pack of beer, eggs, bread, and various other items seemed just fine to purchase all at once . . . until I had to to schlep it all several blocks and up several flights of stairs. Sure there are delivery services, but most people seem to schelp stuff with their own strength of will . . . and creativity.
One common thing you will see if you visit NYC is people pushing collapsible baskets around. They most commonly are filled with laundry or groceries. The look like this:
Well one creative hacker decided to utilize the common basket in a different way - as a bike trailer. Check it out - he or she is even hauling a bike on it!
Pipe clamps and an old broom or mop stick serve as the "hitch" . . .
And a good amount of electrical tape served to attach the stick to the basket.
I can't imagine how this "trailer" would handle on the city roads. The roads feature bumps, cracks, man hole covers, and are generally crappy. Still, the hacker gets an "A" for creativity. I have also seen people use hand trucks as trailers in the city, but I have never had my camera at the ready.
