You're certainly amongst the more cryptic contributors here Ed

The only downside of course is that you have to buy three stickers each time!

It's just a pity really that these things can't be re-cycled (literally). I've bought so many stickers over the years that have gone when either the bike has gone or when the panniers or whatever they've been stuck on has disintegrated with old age. Often the only bit that survives intact is the sticker. I've tried removing them with a hairdryer but it never really works. Unless you're the sort of person that keeps the same bike for ever they're only going to be a record of the last few years. I suppose if you had a series of bikes with suitable steel components you could use fridge magnets instead but (other than a fridge) its been a while since I've owned anything like that.

Other than bikers notching their guns I've wondered who else buys travel stickers. Most places that have any kind of tourist footfall sell them but where do they end up? There's someone down the road from me with a VW camper literally covered in stickers but that's the exception. The few cars I see with them wouldn't be enough to keep the sticker presses rolling. Maybe people just buy them on the spur of the moment, put them in their wallet / purse and forget about them two minutes later. It's just something to be done when you've put some effort in to get somewhere.
