Thanks for the map, Jim. I think I read in the small print that the total distance is 8.2 miles for all 16 venues, which is why I think my pdf will be useful for helping people to decide which of those they are going for.
And as for chaotic free-for-alls, I think there was a vote on one of the crawls - maybe you missed it? - and the majority were in favour of chaos. (A bit like the Conservative party, really.)
