Cycle theft in York is down, according to a meeting on the subject I went to this week. (Amusingly, there wasn't proper cycle parking, just a bit of chain.)
But one of the biggest problems the police face is that of unmarked bikes. There are several dodgy, lockup-garage bike dealers they have their eye on, who flog machines of dubious provenance through Gumtree and eBay using only mobile phone numbers.
When they turn up at said lockup making polite enquiries, however, none of the bikes there register on any database, so there's no proof they've been half-inched.The local register in York is called Operation Spoke - there are regular free registration sessions - and this automatically puts you onto the national Immobilise database.
Hmm; it's no guarantee, as I know from having my Immobilise-registered bike nicked in Twickenham. The police there showed as much interest as if I'd lost a packet of fags in the pub. I never saw it again. But worth doing nevertheless.
Anyway, the owner of this MTB, spotted - literally - at York market this morning, has set up his own bike-marking scheme: vibrant yellow spattered onto jungle green.
How much use this will be in assisting the police if it gets abducted to a lockup I don't know, but it looks striking. No doubt the York heritage lobby will try to stop it.


Of course, it means 'recycling for', not 'recycling of'. This being York, the main Recycling Facility has a special area for walking and bike access. 
But for a couple of hours at low tide (right), when the waters recede, it's perfectly cyclable.
Cramond, like all tidal islands, thrives on stories of careless travellers who get stuck by the tide.
This inspired me to stage my own sit-in: Occupy Wetherspoons, which I did until my train home.
The view the other way is the equally splendid
But the most distinctive thing is the shape of cycle racks, which have a touch of the MirĂ³ about them.
I'm not a fan of people using bikes as ad hoardings - there's little enough cycle rack space as it is in most city centres.
Presumably it's target-market psychology: the manandvan customer is likely to include the person who cycles everywhere - just the sort of person who would notice a parked-bike advert. 
It's constantly busy with cyclists (and, being York, you only have to wait a few minutes for a tandem) and dog walkers.
