"How far can you see in a forest?"
We will be answering the following question raised by Christopher Bishop: 'Suppose we stand in a forest with tree trunks of radius r > 0 and no two trees centered closer than unit distance apart. Can the trees be arranged so that we can never see further than some distance V < \infty, no matter where we stand and what direction we look in? What is the size of V in terms of r?'
