Reflected random walks in the quarter plane arise naturally in probability theory, queueing systems, statistical physics, and combinatorics. In this talk, I will discuss the local time spent on the reflection boundaries. When the drift lies within the cone, the local time converges, without normalization, to a nontrivial random variable as the walk length tends to infinity. I will present recent r
