It's at times like this that I really miss Cyclefest - a bi-annual weekend-ish gathering of the weird and wacky in the cycling department, usually coincident with the Salt Ayre race day of the BHPC, which meant you got all the racers, plus the designers, and hundreds of people 'just having a go' on Morecambe promenade, Salt Ayre racetrack, or around St Martin's College in Lancaster.
Throw in a juggler on a 30" unicycle, various rickshaws, homebuilds, Uncle Wobbly with the SpinCycle and the Wobblebike, and the hill sprint up the college drive, and you have a recipe for a jolly weekend. Sad that it is no more, as it would have provided you with exactly what you're your friend is after - as it did me. Of course I then went and ruined it by actually buying one, but hey...
