Couple questions for you!

At the widest part of the stream, where the bridge is, how wide is it? 

What are the bridges made out of? What's the average radius of the trees?

The stream is about ten feet wide at its widest, which is where the bridges cross. 

The bridges are basically tree trunks, cut down and laid across the stream.  Tree radius should be around 0.75 feet on average (this is for the bottom of the trunk, above the roots).  Bridges will have a similar radius.

[@Drifting Pollen] Would you mind randomizing an arena for me for the sake of fairplay?
