Just wanted to add some info about the Portalock to this thread. I got it off ebay for £7 + p&p and picked it up from the PO this morning.
After a quick test in the garden I am VERY impressed. Our garden is rocky under the topsoil and it took me three attempts to find a spot where it would go in more than 6 inches, but once I found a clear area it went straight in. The shaft is longer than I expected - about 16 inches. Without a spade and a good 15 minutes (or a JCB!) there's no way you could budge it. It is certainly enough to deter an opportunist.
Combined with a decent lock I think I will have peace of mind leaving our bikes on site if we go out in the car for the day.

When we used to "tent camp" more(..at festivals mainly),I used to use a cork-screw dog tether(..shortened and with the top loop welded closed),with a long cable lock wound through stuff..
...but those Portalock things look really good..
..and for the price,if I was looking to secure several hundred quids worth of bike(s),I'd probably get two,while I was at it
I have bought 2 of the dog anchors, they are very long and sturdy looking. The idea is to screw 2 into the ground and then lay bikes flat on topp of them and d lock into the anchor. Only way to get anchors out is by unscrewing, but by locking 2 together, you can't do this, and can't dig them out if all bikes on top.
