How do you deal with a non-carboard shipping container when you need to dispose of it upon getting to your destination?
personally .. I never have used anything but a cardboard Box .. on return I have either bought a box
from the Airline in this case , [KLM, AMS] or taped the stretch of 2 boxes to leave the front wheel on,
or knocked the bike down and repacked it in a box , like it came half way around the world, from Taipei,
in the first place..
In the LBS, the end of the tour cyclists hire the pack and ship service dozens of times a summer , here.
also many arrive on a very nice Bus from Portland , using the PDX airport connections to the pickup point,
which is the Amtrak Train & Greyhound bus stations [a block apart] though the bus is not run by either ..
If you have a hard case , it can get shipped onward.. LBS is about 2 Blocks from the Bus transit center .
