lol, yes WELL DONE ME! (for, ahem, reading Camping magazine
[geek]).
that's what i mean about the appearance of security, Mel, nothing will stop an organised thief, so a couple of sturdy people with knives could have off with it. (it's the same for some of those bike racks as well, i think?)
but given that i was otherwise going to get the Handirack, which also suffers from the same issue potentially, i don't think that it's such a big deal. i would be keeping an eye on the car, i think, in transit, and just wanting it to look like someone had given some thought to security.
longer term, though, a lockable net that secured right through the door frame would solve the problem (although i suspect would be hellish expensive).
