The only time I shipped a bike a got a box from my bike shop and it worked. I was leaving Gainesville, Florida and going to Ithaca (Cornell), NY for a two week conference. My 52/42 with a corncob was not the right gearing for going up Buffalo Street nor riding to a friend's parent's house south of Corning, The box worked.
Did both rides.
The thing that irked me the most was taking a road south from Corning and it was steep but when I got to the top the road was unpaved with HUGE loose rocks and I had to walk down.
Buffalo Street in a 42x18 was tough but doable when I was young.
Oh, this was back when we had freewheels and they had five gears.
