Popped into Halfords today and this caught my eye for £19.99

Not that I need it myself I just thought I'd give you the heads up

I got one from Go Outdoors for a bit less. It's alright but the pole is steel and the tarp is an odd shape if not used as a tent extender. I've since bought a Terra Nova Tarp from Sports Direct for bout £25. With a fibreglass pole robbed from an old tent its also under half the weight!

That's what I used for the WRT. Didn't use poles though. Rigged it up over my bike. Only used 4 alu pegs. Not the lightest available, but a good starting point I thought, having never used a tarp before...
