Sorry if this is a really stupid question but what should I know about travelling abroad with gas? I'm not talking about a proper gas canister. I'm talking about the cans that slot into the single camping stoves.
I've done a lot of camping in the UK and have always just travelled with them in a small crate in the car.
I'm planning to go to France this year. Are there rules about going on the ferry etc I need to know about? They would probably be in the car boot again rather than a trailer or on the roof.
