This is fantastic, and in a way, I wish I'd thought of it first. More bollards than you can shake several sticks at, and some you'll probably be very familiar with. I'm particularly familiar with the 'Vauxhall Three', so I'm glad they're in there.
I haven't worked out how to put links on here yet. It's new Blogger and only seems to offer a series of predesigned templates, wheras i used to go in and edit the template code directly. Can't see how to do that now!
I'm sure I'll work it out - anyway. Remember while you're out hunting for stinkpipes, keep an eye out for bollards too!
