I want a folding kayak

Not posted here for a while but walking along the banks of some of the rivers in sussex and with the current warmth here i really want the sort of kayak i can pack neatly away and take on the train or bus. because i can't drive. i also kind of dream going the length of the Danube Black forest to black sea sort of thing.

I quite like the idea of going down a river somewhere with someone, pulling up on the bank and having sex there and then and camping out b4 going home next day
