Cycling to the Post Office

This morning I took all of our Christmas gifts by bicycle to the post office.  There was no way to carry a 18x18x21" box on my rear rack, so I used the trailer.  Hiding underneath the huge box I had two more boxes of a more normal size (16x16x6 and 4x4x4):

I love biking to the post office.  It is always a little challenge to see how to best carry boxes on a bike.  Once at the post office I can use my bike trailer as a cart and roll it up front.  This is very helpful if I have multiple large packages that would require multiple trips from the car.  Finally it's a great excuse to get out on the bike for a short ride.

For smaller loads baskets work well too:
