My brother in law just re-opened up a roller rink that had been closed for a number of years and actually was turned into a thirft shop at one point. The roller rink had been around for like 30-40 years....
A lot of the original stuff was no longer there, but he figured he needed to update the interior and have it used more for roller hockey and roller derby. So that's what he did, put hockey boards in, new changing rooms, etc... but he still has public roller skating as well.
Here is a link to his place now:
