Yea so what you might say.
But this thing was a cake fpr someone's birthday, and it arrived pristine and perfect like it was sitting on a shelf the entire time.
I used one of my sturdy old style milk crates, sat it on the bottom, cups and plates on top of the container (plastic).
The crate was partly bungee (rubber/hook) on and partly tied on to rack, to let it have some give over bumps vs strapped rigidly to rack.
I do not have any photos, as i was in a huge hurry, but i felt like sharing this small victory with you all. I am really amazed that it was so unaffected, and it took all of my object avoiding skill to dodge all the bumps along the ~1.5 mile route, but that felt good too.
Please feel free to share similar experiences.
