  The strip entropy is studied in this article. We prove that the strip entropy
approximation is valid for every ray of a golden-mean tree. This result extends
the previous result of [Petersen-Salama, Discrete \& Continuous Dynamical
Systems, 2020] on the conventional 2-tree. Lastly, we prove that the strip
entropy approximation is valid for eventually periodic rays of a class of
Markov-Cayley trees.
