Title:  Line Patterns in Free Groups

*Abstract:* Consider a collection of closed curves in a finite graph. The
universal cover of the graph is a tree, and the lifts of the closed curves
make a pattern of lines in this tree. I will discuss when it is possible to
match up two such line patterns with a quasi-isometriy of the tree.
