Of course. It wasn't here originally. It's an early model. Don't see too many of these around the city at all. They're mostly two-way lr three-way nodes, for convenience. I had this one installed here because it made it easier for me to get here and help my friends if it is needed, and anyone who may try to sneak through to the other end would find that they simply couldn't.
Ah. In this case, one-way is the best choice then. Excellent. Anywho, I am on a very tight schedule. We shall introduce next time. This belongs to you.
