climate camp tatdown

Didn't make it to Climate Camp? Did make it but would like to help out a bit more? The camp's nearly finished, but the final stage of tatdown (i.e. returning the common at Blackheath to its former pristine state) is TONIGHT, when the last set of vans will be loaded up between 6pm and 9pm. If you're free, your assistance would be enormously valued. To quote from the email I've just seen on the list:

"If your only contribution to tat down is to come for this 3 hour period then you'll have really helped without all that tiresome hanging about which is the worst bit of this part of the camp."
