Teams of 6 - do kids count as half? :P
I must confess to have only rocked up as Laurence wanted to find his friend, and i didn't want to let him walk by himself. I think the two kids were worth double each. The rest of us (inc the elderly Swedish couple) counted as half. Did the aliens help the team much? Didn't realise there were limits on team sizes.
We were happy to scrape into the top 10!
