TCA is also shrinking, just not as rapidly and it is a much larger club so it will take much longer for it to fade away. Ask any veteran member about York 20+ years ago compared to now. They’ll most likely say it ain’t wht it used to be.
As for LOTS, I don’t have firsthand knowledge but I’ve heard their membership roster isn’t much higher than TTOS. I think both clubs have dropped below 3,000 members at this point.
