I'm currently on tour in the UK, Invararay,Scotland, to be exact. The weather is beautiful!
I plan to take the bus up to Oban tomorrow but they may not take bikes on the bus. But, if I break the bike apart and put it in a bag, they will take it as luggage. I got some "bin" bags and intent to ride to the bus stop, uncouple the bike, tie it together, and bag it for the 1 hour trip north. Ill put it back together once I'm in Oban.
Without the couplers, I'd have to rely on the goodness of the driver.
