Don't throw it in your car on my account, we aren't going to be able to make it tomorrow.
Since I haven't seen the barrels, I don't know how flexible/inflexible the sidewalls are yet. They were used to transport wine, so I think that they are probably pretty durable. I just don't know if a regular bulkhead, like the ones from FF (which I have), are going to be able to make a proper seal. I hope so...
